Dual-polarized array antenna gain method and structure thereof

Abstract

A gain method and structure of a dual-polarized array antenna, comprising: a substrate, a plurality of radiating metal surfaces, a plurality of half-wavelength wires, a first signal feeding network, a second signal feeding A dual-polarized array antenna formed by a network, a first signal feed point and a second signal feed point. After the signal is fed into the first signal feeding point of the first signal feeding network, the signal is increased by one-half wavelength, and then converted by a half-wavelength wire, so that the phases of the radiating metals are consistent, and The current is inconsistent, or the signal is fed in from the second signal feeding point of the second feeding network, and then converted by a half-wavelength wire to make the phases of the radiating metals consistent, and in the case of inconsistent current, the The horizontal and vertical transmit and receive power levels of the antenna are increased.

Description

technical field [0001] The invention relates to an antenna, in particular to a dual-polarized array antenna capable of increasing antenna gain. Background technique [0002] The design of the antenna has the most direct impact on the call quality and signal receiving ability of the mobile communication device. Under the limited space configuration of the mobile communication device, the appearance, PCB, structure and antenna of the mobile communication device must be interdependent. In order to obtain the desired antenna performance. [0003] Therefore, in the traditional array antenna technology, the same single antenna radiation conductors are arranged side by side to form an array structure, such as figure 1 As shown, the dual-polarized array antenna includes a reflective surface 100 , a plurality of radiation conductors 200 , a first feeding network 300 and a second feeding network 400 . The plurality of radiation conductors 200 are arranged in a matrix on the reflecti...

Problems solved by technology

[0004] Although, in figure 1 The antenna sections 302, 402 of the first and second feeding networks 300, 400 of the array antenna are designed to be configured in directions corresponding to the positive 45 degrees and negative 45 degrees of the vertical line of the reflecting surface 100, so that the horizontal and vertical signal receiving The signal effect is not the best, because the dBi value of the power of the array antenna is about 12 and the interference value is between -15 and -20 (the lower the interference value, the better), it is easy to cause signal attenuation and lack of signal mutual interference
