Abstract

The present invention relates to the technical field of antennas and in particular to a dual-frequency triply-fed antenna of an integrated combiner. The dual-frequency triply-fed antenna includes a PCB, a first RF coaxial line, a second RF coaxial line, and a third RF coaxial line. The PCB is provided with a combiner, a dual-frequency singly-fed array element and a high-frequency array element. The third RF coaxial line is connected with the high-frequency array element. A combining end is connected with the dual-frequency singly-fed array element. The combiner is disposed on the front side ofthe PCB. The high-frequency array element is disposed on the back of the PCB. The high-frequency array element and the dual-frequency singly-fed array element are integrated into the same PCB, and the combiner outputs the dual-frequency singly-fed array element in different channels, thereby forming a three-in-one antenna where two high-frequency antennas and one low-frequency antenna are integrated. Due to the up-down arrangement of the antennas and the high isolation performance of the combiner, the three-in-one antenna has excellent isolation between the same frequency and between high andlow frequencies.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a dual-frequency triple-feed antenna integrated with a combiner. Background technique [0002] IEEE 802.11ax, also known as the high-efficiency wireless standard, is a wireless local area network standard under development. IEEE802.11ax supports 2.4GHz and 5GHz frequency bands, and is backward compatible with 11a / b / g / n / ac. The goal is to support indoor and outdoor scenarios, improve spectral efficiency, and increase actual throughput by 4 times in dense user environments. [0003] For the three-in-one antenna, IEEE 802.11ax can currently support up to 4 channels of 2.4G and 8 channels of 5G. If the traditional single-frequency antenna is used, the whole machine needs 12 antennas, which is very costly for customers. . If four dual-frequency dual-feed antennas and four single-frequency 5G antennas are used, eight antennas are also required, which still cannot minimize the cost....
