Abstract

In this paper a coaxial feed square micro strip patch antenna for wireless communication application is presented. Rectangular slot centered on the square radiating patch which is printed on thick substrate is introduced to enhance the bandwidth of the mictrostrip antenna. The impedance bandwidth can be tuned by changing the slot geometry parameters (length and its width) and the dielectric substrate thickness. Many antenna structures are demonstrated to study the effect of these parameters on the resulting bandwidth response. The characteristic analyses such as return loss (RL), Smith Chart, VSWR, Gain and radiation pattern of the antenna have been investigated. The designed antenna provides the bandwidth of 24.1% (1.86-2.37)GHz for -10dB return loss with maximum gain 5.8dB at 2.1GHz.
