Abstract

The invention provides a parallel-fed microstrip patch antenna array, which comprises a first linear array and a second linear array, wherein the first linear array and the second linear array are connected in series through a main feeder line, and a second feeding point is arranged in the center of the main feeder line; the first linear array comprises a first microstrip line, eight microstrip patch units, eight sections of second microstrip lines and eight quarter impedance transformers, the eight microstrip patch units are distributed on the first microstrip line at equal intervals, the eight microstrip patch units are connected with the first microstrip line through the eight sections of second microstrip lines respectively, the center position of the first microstrip line is a first feeding point, and the eight quarter impedance transformers are uniformly distributed on the first microstrip line by taking the first feeding point as a symmetric center; and the second linear array and the first linear array are the same in structure. The parallel-fed microstrip patch antenna array provided by the invention is simple in design, few in patch units, small in antenna array size, relatively large in gain and relatively wide in 3dB bandwidth.

Description

technical field [0001] The invention belongs to the field of microwave technology and antennas, and in particular relates to a parallel-fed microstrip patch antenna array. Background technique [0002] As the transceiver device in the communication system, the antenna has a direct impact on the performance of the communication system. With the increasingly higher requirements for communication quality in the communication field, products such as antennas not only have high requirements for their own performance, but also have great requirements for shape, size, and ease of processing. Due to the advantages of small size, light weight, low profile, easy conformality, easy integration, and low production cost, the microstrip patch antenna has a wide range of applications in the fields of mobile communications, satellite communications, missiles and telemetry, radars, and aircraft antennas. application. The power capacity of a single microstrip patch antenna is small, and the...
