A Novel High-Performance Patch Radiator

الملخص EN

A novel two-layer highly efficient directive E-shaped patch radiator is described.

By modifying the geometry of a rectangular patch and by introducing two slits, the size of the original rectangular patch is reduced.

Further reduction in the size is achieved by stacking E-shaped patches.

Both gain and efficiency of this modified antenna is increased by 16%.

It is also observed that by introducing EBG structure, the bandwidth of the antenna is increased by 10.5% approximately.
