Abstract

In this paper a novel circular microstrip patch antenna loaded with “Swastika (卐)” shaped slot with 2.4 GHz frequency reponse is investigated and designed. A swastika shaped slot is etched on center of circular patch (radius of 17 mm and thickness of 0.5 mm). The proposed swastika shape slotted circular microstrip patch antenna (CMSA) is designed and analyzed by using Finite Element Method (FEM) based High Frequency Structure Simulator (HFSS™) EM software. The radiation pattern, return loss and VSWR plots are presented for the proposed antenna. Good return loss and VSWR was achieved for the proposed geometry as depicted in the plots. The presented antenna can be used at 2.4 GHz ISM (Industrial, Scientific and Medical) band applications. Another antenna with modified structure is also presented which gives triple band frequency response.
