A novel high gain and wideband microstrip antenna

In this paper, a high gain and wideband microstrip antenna is proposed.By utilizing a reflector cavityto implementing the single direction radiation of the microstrip antenna, also, two parasitic patches were added to adjust the impedance match and to improve the radiation characters.Basing these theories, a wideband microstrip antenna which operates at the frequency bandof 5.85~7.18GHz is designed and implemented.During its operating frequency band, the voltage standing wave ratio is acquired less than 2.0, and the gain of more than 10.5 dB is acquired.Meanwhile, the antenna principle and design mentality are given, simulation results of the proposed antenna are also illustrated.
