High gain multiple resonance Ku-band microstrip patch antenna

Abstract

A Ku-band patch antenna loaded with notches and slit have been designed and simulated using CST Microwave studio. Multi-frequency band operation is obtained from the proposed microstrip antenna. The simulated 10 dB impedance bandwidth of the rectangular patch microstrip antenna is 600 MHz, 520 MHz and 382 MHz for the resonance frequency of 12.41 GHz, 14.44 GHz and 16.64 GHz respectively. The gain and directivity of the proposed antenna are presented at different Ku-band frequencies.
