Abstract

The invention discloses an equilateral polygon patch circular polarized antenna. The antenna comprises an equilateral N-gonn metal patch, a microstrip feed line connected with the feeding port of themetal patch, a PCB board located under the metal patch, and a floor located under the PCB board. The floor is provided with a hollowed equilateral N-gonn empty slot. A rectangular patch is arranged inthe empty. The side of the empty slot is longer than the side of the metal patch, and the empty slot is located directly under the metal patch. A circular seam between the empty slot and the metal patch forms a capacitive load. The metal patch and the rectangular patch are coupled and short-circuited to form an inductive load. N is a positive integer greater than or equal to 6. According to the invention, the circular seam is formed between the empty slot and the metal patch to form the capacitive load; the metal patch and the rectangular patch are coupled and short-circuited to form the inductive load; the antenna can realize circularly polarized directional radiation in a working frequency band; in addition, the antenna adopts single-point feeding design; the structure is simple; an external circular polarization feeding network is not needed; and a great circularly polarized radiation effect is formed.

Description

technical field [0001] The invention relates to the field of microwave technology, in particular to a circularly polarized antenna of a regular polygonal patch. Background technique [0002] With the development of modern communication technology, pure linear polarization is difficult to meet the communication requirements. Therefore, circular polarization has attracted people's attention, and its current applications are becoming more and more extensive. The practical significance of circularly polarized antennas is mainly reflected in: [0003] 1. Circularly polarized antennas can receive incoming waves of any polarization, and their radiated waves can also be received by any polarized antenna, so circularly polarized antennas are generally used in electronic reconnaissance and jamming; [0004] 2. The rotation orthogonality of circularly polarized antennas is widely used in applications such as communication, radar polarization diversity, and electronic countermeasures;...
