Abstract

A dipole antenna which can achieve good performance in a wideband of 820 MHz (1.73-2.55GHz, corresponding to a 38.3% bandwidth) is analyzed and implemented. A unique feed network with two overlapping cross-shaped patches printed on both sides and a 50Ω SMA connector settled in the center is designed to avoid the use of a balun which requires large space and adds the complexity of design. The parallel strip line is utilized to improve the impedance matching. Effects of the width and length of the radiation arm and the parallel strip line on the performance of the proposed antenna are also studied.
