Abstract

The invention provides a radiation patch array and a planar microstrip array antenna. The radiation patch array is composed of n columns of radiation patch linear arrays. The radiation patch linear array is composed of m rows of radiation patch units. The radiation patch unit comprises a cross-shaped power division network and two rectangular patches. The cross-shaped power dividing network is ofa four-port structure, a left port and a right port are respectively connected with a rectangular patch, and the rectangular patches are excited in a parallel connection mode. And the upper ports andthe lower ports are respectively connected with the upper ports or the lower ports of the adjacent cross-shaped power division networks in the same column in series. The radiation patch linear array excites the rectangular patches in a parallel series feed mode, constructive radiation superposition is achieved in the wide edge direction of the rectangular patches, the length of a transmission lineis reduced by one time, meanwhile, the size of the antenna is reduced, and the cost of the antenna is effectively reduced. Meanwhile, because the feed loss is reduced, the noise performance of the array is improved, and the radiation efficiency and the gain bandwidth performance of the array are improved.

Description

technical field [0001] The invention relates to the technical field of microstrip antennas, in particular to a radiation patch array and a planar microstrip array antenna. Background technique [0002] In the field of modern mobile communication, the antenna is the core device of wireless microwave communication, and its envelope characteristics and integrability are more and more important to the communication quality. Compared with commonly used microwave antennas, microstrip antennas have the advantages of small size, light weight, simple fabrication, easy integration, and convenient conformality. Microstrip antennas can be widely used in airborne radar, satellite communication, mobile communication and satellite TV systems, significantly reducing the space occupied by communication equipment and improving the performance of communication equipment. [0003] Due to the low gain, wide beam and low radiation efficiency of the microstrip antenna unit, in order to achieve th...
