Bandwidth Enhancement of Arrow- Head Microstrip Patch Antenna

Abstract

The Microstrip Patch Antenna are widely used in Mobile and Satellite communication, Global Position System Applications, handheld devices etc. Microstrip patch antennas have advantages like light in weight, less volume, inexpensive, small size and ease of fabrication and conformity. Also, the microstrip patch antennas are also capable to provide dual and circular polarizations, dual-frequency operation, broad bandwidth range, etc. In this paper, an optimised design of Microstrip Arrow-head Triangular shaped slot antenna is proposed. Double slot is introduced in Micrstrip Arrow-head Triangular shaped slot antenna. The dimensions of the Triangular shape is also modified. The compared results demonstrates better performance of the proposed antenna.
