Design of Slotted Circle Split Ring Micro Strip Patch Antenna Connected with Rectangular Shaped Meta Material Structure to Enhance Parameters at 1.8 GHz

Abstract

This paper extends for Rectangular Micro strip Patch Antenna (RMPA) along with Meta material which has Design of “Slotted Circle Split Ring with Rectangular” proposed for better improvement in the impedance bandwidth and reduction in the return loss at operating frequency 1.8GHz. The proposed antenna is designed at a height 3.2 mm from the ground plane by using CST-MWS software.  At 1.8 GHz the bandwidth is increased up to 30MHz in comparison to RMPA alone. The Return loss of proposed antenna is reduced by-36.95dB. This antenna is small size, cheap, compact and easy to fabricate, and achieve good radiation characteristics with higher return loss. In this paper, return loss basically defined as system becomes stable with reduced return loss.
