Abstract:A novel substrate integrated waveguide slot array antenna loaded with dielectric resonators was proposed, and a simple and quick design approach for this antenna was given. With the help of Ansoft HFSS for further optimization design, good results could be obtained. Using the design approach proposed, a substrate integrated waveguide four-element transverse slot array antenna loaded with cylindrical dielectric resonators at K-band was designed. The simulation results show that the bandwidth of -10dB return loss is about 450MHz, and the maximum gain of 11.8dB and radiation efficiency of 92% are obtained.
Keywords:dielectric resonator  substrate integrated waveguide  array antenna  return loss  gain  efficiency
