Design of a Novel Dual-Frequency Antenna for Wireless Communication Applications
The purpose of the paper is to develop a microstrip patch designed for dual frequencies of 2.45GHz and 4.75GHz. A new design of two circular patches with a small ring slot in the middle to get the dual band operation is proposed in this paper. It is a multiple patch method for getting dual frequency operation with a single feed point. The simulation and measurement were performed and the dual-frequency bands with a return loss less than -10dB were achieved. This design aims to develop a novel design for achieving a dual band operation for ISM band, RFID(2.4GHz), and radar systems(4.75GHz) applications.
