Abstract :
The paper presents the radiation performance of a dual frequency broadband hexagonal microstrip antenna. The simulation of hexagonal antenna designed on glass epoxy FR-4 substrate with appropriate dimensions is carried out using IE3D simulator. The optimization of side lengths and angles of hexagonal geometry is carried out to achieve much improved bandwidth (10.2%) and dual frequency performance. In the range of frequency where antenna is displaying broadband performance, the directivity, gain and efficiency are almost constant. The radiation patterns obtained at five frequencies within this frequency range provides identical shape with direction of maximum intensity normal to the patch geometry. The performance of this antenna is compared with that of a rectangular patch antenna.
