Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a wide-beam dielectric resonator antenna, which can be applied to wireless communication systems such as mobile satellite communication and satellite positioning. Background technique [0002] With the rapid development of wireless communication, many wireless communication systems put forward higher requirements on the signal coverage of the antenna, and require the antenna to provide a larger signal coverage. Therefore, wide-beam antennas have received more and more attention and attention. [0003] The dielectric resonator antenna is a resonant cavity antenna. Since it was first proposed in 1983, the research on the dielectric resonator antenna has gained widespread attention. Compared with traditional antennas, dielectric resonator antennas have the advantages of higher design freedom, higher radiation efficiency, various feeding forms, and various antenna modes. However, th...
