Abstract

Abstract The most important characterizing parameters which determine the antenna performance are axial ratio bandwidth, impedance bandwidth and gain of wireless systems. The improvement of these parameters are presented in the proposed antenna. Basically, the proposed design consists of an inverted L-shaped microstrip feed line and modified ground plane. The size of the antenna is 0.4 × 0.28 × 0.0128 λ 0 (where λ 0 be the free space wavelength at f r of 2.4 GHz). The designed antenna has been fabricated and the measured results of fabricated antenna are compared with the simulated results. It is found that the results are very good in agreement. Novelty of the research work is the improvement of axial ratio (less than 3 dB) bandwidth. As a result, the antenna is circularly polarized for a good amount of bandwidth which is desired in the modern communication system. Circularly polarized antenna is able to transmit and receive both vertically and horizontally polarized electromagnetic waves.
