Abstract

A compact printed dipole antenna with enhanced impedance bandwidth is proposed for wireless applications in this paper. This antenna consists of a pairs of radiation metal arms, a microstrip-to-slot transition and a linear tapered slot. The linear tapered slot is etched into the center of the radiation metal arms. With this structure, the bandwidth of a conventional dipole antenna is improved significantly. A prototype of the antenna is fabricated and tested for demonstrating the effectiveness of the design. The measured results show that the proposed dipole antenna can achieve a gain of 1.9-4.5dB across a 101.7% measured bandwidth from 2.08 GHz to 6.38GHz.
