H-Shape of a trapezoidal neck High-Gain Patch Antenna

In this study, a microstrip antenna simulated between 1-11 GHz is manufactured and presented results with measurements. Then simulation results are presented. |S11| simulation and measurement results almost show perfect agreement. S11, the input reflection coefficient parameter has the value of -31.24 dB at the center frequency and the resonance frequency has the gain value of 11.21 dBi at 8.24 Ghz. Especially, the antenna has been exclusive with Slits and trapezoid centre piece.
