A comparison diagram of the second group of standing wave ratio versus frequency variation generated by the band antenna, and FIG. 7 is a comparison of the third set of standing wave ratio versus frequency variation generated by the three-input eight-band antenna of the preferred embodiment of the present invention. And FIG. 8 is a comparison diagram of the standing wave ratio versus frequency variation of the fourth group generated by the three-input eight-band antenna of the preferred embodiment of the present invention. As shown in Figures 5 to 8, the A-band, B-band, and C-band bands in Figure 5 are categorized as the eighth band (704 MHz to 746 MHz), the seventh band (824 MHz to 894 MHz), and the sixth band ( 880MHz to 960MHz), the D-band, E-band and F-band in Figure 6 are the fifth frequency band (1710MHz to 1880MHz), the fourth frequency band (1850MHz to 1990MHz) and the third frequency band (1920MHz to 2170MHz), respectively. The G-band in the figure is the second frequency band (2500MHz to 2690MHz), and the H-band in Figure 8 is the first frequency band (3410MHz to 3590MHz). The vertical axis of Fig. 5 to Fig. 8 is the standing wave ratio (SWR) of the antenna 2 of the present invention, and the gain value of the return loss is linear with each other, and can be calculated by calculation. The standing wave ratio is converted to the gain value of the foldback loss, and the horizontal axis is the resonant frequency of the antenna 2 of the present case. The standing wave ratio value varies with the frequency. Generally, the frequency band with a standing wave ratio value of, for example, 3 or less represents that the antenna has a good effect in the frequency band. Therefore, as shown in the fifth to eighth figures, in the embodiment of the present invention, The standing wave ratio of the A to H frequency band is far less than 3. Therefore, the antenna 2 of the present invention can indeed generate the eighth frequency band A to H based on the existing LTE-A standard and the use standard in the field, that is, the first frequency band to the eighth frequency is applicable. The frequency band, and the frequency bands generated by antenna 2 in this case all have good performance.

In summary, the three-band antenna of the LTE-A smart phone in this case transmits the first radiating portion, the first segment portion, the second radiating portion, the second segment portion, and the third portion in a special form. The segment portion, the third radiating portion, the fourth segment portion, the fourth radiating portion, the first branch portion, the fifth segment portion, the sixth segment portion, and the seventh segment portion achieve high efficiency and high gain Band resonance, which is the technical limitation of a planar inverted-F antenna with a complex array of two feed points, in order to achieve multi-band resonance in the prior art. In this case, a single antenna with three feed points is used to achieve the eight-band. The effect of resonance, so the 380-band antenna of the LTE-A smart phone in this case not only effectively improves the performance and improves the gain, compared with the conventional inverted-F antenna with two feed points of the complex array. The antenna can be further miniaturized and the manufacturing cost can be reduced.

This case has been modified by people who are familiar with the technology, but it is not intended to be protected by the scope of the patent application.
