suspended microstrip; rectangular patch; X-band with dielectric resonator loading; radiation pattern; impedance bandwidth 12.3 %; Suspended Microstrip Patch Antenna with Dielectric Resonator Loading for Enhanced Bandwidth
This paper reports experimental investigations on suspended microstrip rectangular patch
antennas at X-band with dielectric resonator loading. By placing the resonator at
appropriate position on the patch, an impedance bandwidth of about to 12.3 % and an
improvement in gain over the unloaded case by about 1 to 2 dB have been achieved, without
much change in the radiation pattern.
