Abstract : In this paper, we present a high gain, dual beam pentagonal patch antenna. The pentagonal geometry is inspired from a rectangle patch antenna and a triangle patch antenna. The architecture of the antenna resembles an irregular pentagon comprised a triangle placed on top of a rectangle. FEM is used for the analysis of the antenna design. The pentagonal antenna gave good reflection and radiation characteristics with a 2:1 VSWR bandwidth of 8.1 % at resonant frequency. As we combined the geometry of a rectangle and a triangle for the pentagonal design, the single pentagon patch antenna radiated two directional beams with a peak gain of 6.1 dBi at resonant frequency. Even though the pentagon patch had slightly less gain than the rectangular patch, it had an additional advantage since it radiated in two directions. The proposed pentagonal antenna architecture can be used in applications where there is a need to produce a dual beam without the need of any additional circuits for switching.
