Description of the Invention: [Technical Field of the Invention] The present invention relates to a wafer type antenna, and more particularly to a prior art frequency-early dipole chip type antenna. The wireless communication products of the Internet are gradually becoming an important medium in human life, and the antenna is in the middle of wireless communication products. The m number can be ^ and ^ complete the transmission of energy' and then achieve wireless communication. Demand. However, with the multi-band communication: · ' Therefore, it is bound to integrate multiple single-frequency antennas into one multi-frequency antenna. The development of force 1 has caused various kinds of communication products and technologies to spring up, and it is mature. The volume of the product is also gradually tend to be light and thin, and the size of the volume is even more important. Whether the target is light, thin or short; the antenna is used to transmit or receive electromagnetic waves from the operating frequency (radlatlQn) and return loss (returni〇ss). The antenna antenna (antennagain) # parameter to know the characteristics of the antenna; and today's wireless production = the antenna used must have small size, sex, etc., in order to get a wide range of market access. Differentiated by the placement position, the wireless antenna can be divided into two types: the external spot is built in. The external antenna has been gradually replaced by the 天线 antenna. In the Republic of China Announcement No. 507399 "Double Frequency Fiberglass Chip Antenna" patent, which reveals a dual-frequency fiberglass chip antenna, which is formed by forming a radiant metal wire on a glass fiber material. Adjusting the length and mode of the radiating metal wire to adjust the resonant frequency and frequency ratio of the wafer antenna to obtain dual-band operation. The dual-frequency fiberglass chip antenna is placed on a microwave substrate having a ground plane, and the ground plane and the signal ground end In connection with the ruler of the microwave substrate, wherein the microwave substrate is located directly under the double-frequency fiberglass (9) antenna, the ground has a size of, for example, about 9χ5^2. The microwave substrate can be regarded as a circuit board of a wireless communication mobile phone, that is, the chip antenna should be used as a Bluetooth or wireless local area network system on the wireless communication mobile phone. However, the first (low frequency) frequency band and the second of the above-mentioned prior art technologies are The (high frequency) band has only a narrow -10dB bandwidth, which is about 200MHz and 1000 liters, respectively, which is less suitable for the user's broadband 1269490.
