Bandwidth enhancement of hexagonal patch microstrip antenna with several approaches

الملخص EN

In this work we calculated the bandwidth of hexagonal patch shape microstrip antenna operate at 2.4 frequency.

We found that the bandwidth is narrow if dielectric constant is small.

In order to widen the bandwidth we suggest made a slot in the ground plane of the microstrip antenna.

The bandwidth became 148.8% when we use the foam after making two wide slots in the ground plane of microstrip antenna.

The procedure was applied to different substrate with different dielectric constant, the results show an increase in the bandwidth in both case.

The simulation is done by using finite difference method time domain FDTD programing by MATLAB tools.
