Abstract

In this paper a new technique for reducing the resonance frequency is proposed using two C-slots on the patch which giving the capacitive effect. The unloaded patch antenna has resonance frequency of 3.96 GHz where as the loaded C-slot patch antenna has resonance frequency of 3.28 GHz. The unique features of our proposed C-slot patch antenna are similar radiation patterns with respect to unloaded patch antenna, high gain, 17.17% reduction in resonance frequency and very good front to back ratio. From the E-Field distribution on patch it can be observed that concentration of electric field is more on the two C-slots on patch antenna which producing capacitive effect and this capacitive effect nullifying the inductance at 3.28 GHz which can be shown from Input impedance curve.
