A dielectric resonator loaded substrate integrated waveguide slot array antenna structure is proposed and a simple and fast design method is given. By Ansoft HFSS simulation software to further optimize, you can get good antenna design results. A quadrupole transverse slot array antenna loaded by K-band cylindrical dielectric resonator is designed with the designed method. The simulation results show that the antenna has a -10dB return loss bandwidth of about 450MHz and the maximum gain is 11.8dB Radiation efficiency of 92%.
