Modeling and Designing of Circular Microstrip Antenna for Wireless Communication

Sachin S. Khade, Prassana L. Zade, Neelam Choudhary

Abstract

The purpose of this paper is to presents modeling and designing of Circular microstrip patch antenna. The S and Z parameters of a Circular patch microstrip antenna are investigated and optimization is performed either by varying the Patch radius 'R' with keeping dielectric constant '¿r' fixed and by varying the dielectric constant '¿r' of a material with keeping Patch radius 'R' constant. The antenna design and simulations carried out and reasonable value of impedance, VSWR, return loss of Circular patch antenna are examined and compared. It is able to achieve a return loss less than -35 dB and VSWR < 2 at 2.4 to 3.4 GHz.
