Abstract :
The simulation results of rectangular patch antenna with a rectangular notch with and without air gap are reported in this paper. The structure has three layered structure in between conducting patch and the ground plane. It is found that rectangular antenna having an appropriate size of rectangular notch resonates at two different frequencies and also provides much improved bandwidth. On the introduction of an air gap of 1.5 mm between the dielectric layers, this antenna resonates only at a single frequency but with further improved bandwidth. Improved gain, efficiency and directivity of antenna may be obtained under this condition.
