Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a wide-beam dielectric resonator antenna embedded with metal posts. Suitable for wide beam antenna applications. Background technique [0002] In recent years, the application and research of dielectric resonator antennas have received more and more attention, especially in the field of microwave radio frequency. In 1939, Richtinger theoretically proved for the first time that dielectric spheres and dielectric rings can play the role of microwave resonators, and proposed the concept of dielectric resonators. As a resonant antenna, a dielectric resonator is composed of low-loss microwave materials. The higher the relative permittivity, the larger the quality factor and the smaller the bandwidth. Usually, in order to obtain a wider bandwidth, a dielectric material with a relative permittivity of about 10 is generally selected to make a dielectric resonator antenna. Because the ...
