Multi-Frequency Wideband Microstrip Patch Antenna for WLAN/ HIPERLAN/ SATELLITE Applications
In present paper, a novel miniaturized design of a multi frequency rectangular microstrip patch antenna is designed and simulation results are presented in this paper with broadband behavior for WLAN and HYPERLAN and SATELLITE applications is proposed. The proposed antenna has Multi frequency bandwidth of about 385 MHz (3.282-3.672GHz), 517MHz (5.114- 5.631GHz) and 1111 MHz (5.917-7.028GHz) at -10 dB return loss which is sufficient to make the antenna useful for WLAN/ HIPERLAN/ SATELLITE operation. The maximum achievable gain over the entire frequency band is close to 5 dBi. The resonance frequencies can be controlled by adjusting the dimensions of the ground plane.
