Abstract

In this paper, a small printed antenna for mobile handset and WLAN applications is presented and discussed. The proposed antenna is a printed crescent shape monopole which is mounted on top of a defected ground plane. A 50 ohms microstrip line is used for feeding purposes. The performance of the proposed antenna was analysed and optimised to cover a wide bandwidth from 1.7 to 3.1 GHz. For validation, the antenna prototype was fabricated and tested. The performance of this antenna was characterised in terms of the reflection coefficient, radiation pattern and power gain. The calculated and measured results in terms of reflection coefficient show good agreement. The simulated gains and radiation patterns are given to fully describe the performance of this antenna.
