Dual-Frequency SIW cavity-backed slot antenna using two high-order modes
In this paper, a novel dual-frequency substrate integrated waveguide (SIW) cavity-backed slot antenna using two high-order modes is presented. Determined by the locations and types of the feeding and radiator, the high-order hybrid mode (superposition of TM310 and TM130) and another higher-order mode TM320 in SIW cavity are excited by an inductive window for dual-band application in K-band. The simulated results of the proposed antenna show that the 10-dB impedance bandwidths at resonant frequencies of 21.2 and 26.1 GHz are 400 MHz and 800 MHz, and the realized gains at boresight direction are around 10.7 and 11.9 dBi, respectively. Including its high gain, the designed dual-frequency antenna has the advantages of high front-to-back ratio and low cross polarization level.
