新型X波段圆极化介质谐振器天线
Novel X-band circularly polarized dielectric resonator antenna
摘要
Abstract
A novel circularly polarized rectangular dielectric resonator antenna operating at X band is proposed.The antenna is constructed by housing a rectangular dielectric resonator into the dielectric substrate,and is excited by an U shaped microstrip feed line.The ground plane of the antenna adopts Defected Ground Structure(DGS) that can be adjusted by the size of the corners of the defected structure to produce two orthogonal modes and achieve circular polarization,which effectively decreases the complexity of feed networks for some circularly polarized antennas.The simulated impedance bandwidths are 8.88-10.22 GHz and axial ratio bandwidths are 9.56-9.92 GHz,which suit for satellite broadcasting,aeronautical radio navigation service,and radio positioning.关键词
