Ku Band microstrip patch antenna

In this study, a microstrip antenna operating at 11.56 GHz is designed and simulation results are presented. The antenna air thickness is 5 mm and the gap between the antenna and ground is 2.5 mm. Cell size is regarded as 0.75 mm. The antenna was simulated in the frequency range of 5-15 GHz. S11, the input reflection coefficient parameter has the value of -27.50 dB at the center frequency. The resonance frequency has the gain value of 4.72 dB.
