Abstract

The invention provides a dielectric resonant antenna with an adjustable band trap characteristic, belonging to the field of radio communication, and particularly relates to a dielectric resonant antenna with an adjustable band trap characteristic. The problem that at present band trap-adjustable dielectric resonant antennas hardly eixst is solved. The dielectric resonant antenna comprises a dielectric resonator, a step impedance microstrip line, a dielectric substrate, a defective floor, a first radio frequency switch, a second radio frequency switch and a third radio frequency switch, and ismainly used in the field of radio communication.

Description

technical field [0001] The invention belongs to the field of radio communication, in particular to a dielectric resonant antenna with adjustable band trap characteristics. Background technique [0002] In 1983, Professor Long of the University of Houston proposed the dielectric resonant antenna for the first time. Dielectric resonant antennas have a series of advantages such as miniaturization, light weight, high radiation efficiency, flexible design, and easy excitation, and have been continuously researched in the past thirty years. The research results mainly focus on the study of broadened frequency band, circular polarization, high-order mode, high gain, high frequency band and array. The existing research results show that the dielectric resonant antenna has the potential of ultra-wideband application. Wideband antennas with notched characteristics can avoid electromagnetic interference from relatively narrowband systems. In order to achieve flexible switching betwe...
