Description of the invention: [Technical field to which the invention pertains]. [001] The present invention relates to a dual-frequency antenna, and more particularly to a dual-frequency fin dipole antenna. [Prior Art] [002] The data transmission of many electronic products has gradually changed to data transmission by wireless communication protocol. Different wireless communication ages have been proposed for different transmission distances, transmission rates, and transmission environments, and the bandwidth and frequency of various wireless communication applications are different. _] The traditional antenna is mostly tubular-shaped, and its length is set for the non-communication protocol. The antenna is conjugated to the antenna, so that the antenna can receive or radiate wireless according to the standard frequency. Electric wave. ^ [_ However, the transmission _ antenna is exposed outside the electronic device, guide, view. At the same time, a single antenna can usually only cooperate with a single wireless communication protocol = signal, for example, the electronic paste (four) communication protocol sends and receives wireless to the external long-distance scale network into the ___ 乂 and different specifications of the antenna. In this way, the two antennas that borrowed two or more of the core U also occupy the appearance of the electronics and the miniaturization. For the single-antenna can not be caused by the library: the second is not conducive to the electronic skirting, 230, 578 proposed a dual-frequency dipole antenna material for the purpose, the US patented projectile with - coaxial double wire grounding and feeding signal, which contains two radiators 'The radiating part of the fundamental frequency of the two light resonances, Μ 你 灰 —' and each antenna body contains different / solid body with two different resonance bases 200917572 frequency 'in response to double lying requirements. At the same time, the two radiators respectively generate resonance--half-wavelength signal' and add (10) to form - money shouting, and the effect of reducing gain. However, 'US7, 23G, 578 is still an external antenna age meter, which is not conducive to hiding in electronic devices. [005] In response to the demand for conventional antennas, a printed antenna or a flat panel antenna has been proposed to hide the antenna inside the electronic device. In such an antenna, a metal foil or a metal ore film is placed on a substrate, and a special pattern is formed so that the metal foil or the metal has a common frequency. This kind of antenna can be hidden inside the electronic device, so it is easy to increase the number of antennas, meet the needs of multiple platforms, or make a dipole antenna form to enhance the added effect. For example, U.S. Patent No. 6,621,464 discloses a dual-frequency dipole dipole day m& two-beam projecter, each having two resonant fundamental frequency non-radiation portions. The two light-emitting bodies are grounded and fed with a simple line to form a dipole antenna. Although US6, 62M64 bribed the problem of space occupied by the antenna, when installing, the two radiators must be installed separately, and the relative position between the emitters has the effect of combining the gain. Therefore, it takes a lot of time to install the two-body body - the relative position of the projectile, making the balance uncomfortable. SUMMARY OF THE INVENTION The purpose of the present invention is to provide a dual-frequency short-circuit dipole antenna to solve the dual-frequency & Problems or disadvantages of polar antennas. 200917572 The body has i human end and - spoke (four), the forest body has a slot, suitable for the general: 'Tau miscellaneous light end cut into the first - light shot and one, purchase (four) (four) fundamental frequency, to face Shoot or receive a wireless signal of a different frequency. The short-circuited body is connected to the feed of each of the fortunate emitters. [=]The effect of this batch is that two-spoke (four) and short-circuit body-body forming, = the body (four) position has been set, because the body can be - and set in the silk or want to ^... pure body and New Zealand Adjusting the relative position of the two light emitters between the roads, the == set 'does not need to be extra cost [_« under the treacherous form; ^ 増 benefit effect.

(4) Referring to "Figure 1" and "Figure 2", the substrate] can be printed on a 200917572 private board, a plastic board, or a board made of any insulating material. The substrate 110 can be a braided device housing. Some parts, for example, as shown in Figure 2, are placed in an electronic clothing unit. The second radiator 120 and the short circuit body 130 are disposed on the substrate 11A. The substrate 110 is used to support: a dry emitter 12〇 and a short-circuit body 13〇 to maintain the shape of the two light emitters 12〇 and the newway body 130. The two radiators 12 and the short-circuiting body 13 are integrally formed, and the like can be cut by a metal sheet and adhered to the substrate 11 () by an adhesive. Alternatively, the two radiators 12 and the short-circuit body 13 may be formed by a printing or etching technique to form a conductive medium layer on the substrate, and the conductive medium layer is designed into a predetermined pattern to form the two-radiator 100 and the short-circuit layer 130. [〇13] Referring again to the "figure diagram" and "figure 3", each radiator 12 has a long rectangular shape with a feed end 120a and a radiation end 120b, and each radiator 120 has a slot. I2〇c, the slot 120c extends from the middle portion of the radiator 120 or the portion close to the feeding end 12ua toward the wheel end 120b, and forms an opening at either edge of the light-emitting end, and cuts the radiation end 120b into a first a radiating portion 121 and a second radiating portion 122. In the present embodiment, the slot 120c is L-shaped, and one end of the slot 12〇c is located in a portion of the radiator 120 that is close to the feeding end 120a, and the other end is on one side of the radiating end 120b, so that the first The radiating portion 121 and the second light projecting portion have different lengths and constitute different resonant fundamental frequencies, generating a half-wavelength signal. Therefore, the radiator 120 can be used to radiate or receive different operating frequencies, for example, an indoor wireless region of 24 GHz. The network and the 5.2 GHz outdoor high-frequency long-distance wireless network are shown in Figure 3. That is, in the signal generated by the radiator 120, there is a large signal intensity at the portion where the frequency of the frequency is 2.4 GHz and 5.2 GHz. <Yes, in the MIMO (multiple-input-multiple-output) protocol, it is responsible for the transmission and reception of two channels 200917572 at the same time. The feed terminal 12A has a signal contact I23 for connecting the signal line of the same line to feed the electric city, and the same rail/outer ground protection net can be electrically connected to any of the radiators 120. At the same place, the first-light shot 31m and the second Xing-chang shot and 2 respectively constitute different resonant circuits, and lightly radiate or receive wireless signals. The direction from the feed terminal 12〇a to the light emitter end 12〇b is the fundamental frequency resonance direction. [〇14] As shown in the "Fig. 1", the short-circuiting body 130 is mainly used to electrically connect two light-emitting bodies and to provide mechanical connection. Cut into a two-shot body with a piece of metal! In the case of 20 and the short-circuiting body 13〇, the two-spoke 12〇 and the short-circuiting body (10) can be cut by a single-metal piece and formed into a body. At this time, the short-circuiting body 13 is electrically connected to the second beaming body 12G. Moreover, the direction and the angle between the mechanical targets can be exerted, so that the radiator 12G produces a dipole gain effect along a specific direction. At the same time, since the two radiators 12〇 and the short-circuiting body 13〇 are formed by the body, the metal sheet of the two-wheeled body i2〇 and the short-circuit body 13〇 is fixed to the substrate n〇 in the process of the second radiator 12G. And the angle is naturally fixed, and it is not necessary to re-adjust the relative position and the central angle between the radiators 12 in the process. In the present example 2, the short-circuiting body 13 is L-shaped, and its two ends are respectively connected to the feeding end of the two radiators (10). Since the middle portion of the short-circuiting body (10) exhibits a bending angle of 9 degrees, the orientation of the second body 120 can also exhibit an angle of 9 degrees. Of course, the short-circuited body's «'s lay-up' is a two-sided body, and the mechanical connection and electrical connection effect can be achieved. Referring to the "Fig. 4" and "5th" diagrams, the distance between the two rides is 90 degrees. It only needs less than 180 degrees to allow the two light emitters to produce the yarn gain. This can be a paste, as shown in Figure 4, 200917572, or as a pure corner, as shown in Figure 5. [016] After the two light emitters 120 are electrically connected by the short-circuiting body 130, the short-circuiting body 12 is further connected to the grounding wire, for example, the grounding net of the cable outer ring of the coaxial cable, so that the feeding end of the two radiators 120 L2〇a together form a node. When feeding a signal or sensing a radio wave signal, the two radiators generate a second resonant fundamental frequency, and the half wavelength of the two resonant fundamental frequencies is equal to the first radiation portion 121 and the first The length of the second radiating part (2). The resonance of the radiator 120 is combined with each other to form a complete full wavelength. The second awning can produce a dipole gain effect, plus or the ability to receive signals. f [017] Please refer to "6th Plan", "7A", "7B" and "7C", which is the field shape of the first embodiment. In the figure, the X-axis is the reference reference line, and the two radiators (4) are symmetrically based on the X-axis and are on both sides of the X-axis, and are respectively lost to the X-axis by 11 electric power, 11 summer 7A, and on the X_Z + surface. According to the quantity and the fruit, the system is inclined toward +X (0 degrees), so there is still an electromagnetic field distribution in the +Y and -Y directions at the + and -, and the -120 position. A slight gain effect. Referring to the "Section 7", the distribution to the electromagnetic % corresponds to the overlap on the x-axis, and the extension + χ direction extends the omnidirectional.
