Circular ring loaded flower shaped antenna for triple band applications

Abstract

This article presents the design and analysis of triple band micro stripantenna for various wireless communication applications. The deigned antenna consists of circular ring loaded flower shaped antenna having a circular slot in the centre of the patch. The center slot in the middle of the patch is responsible for improving the reflection coefficient of the antenna. The antenna shows triple band characteristics with resonating frequencies at2.52 GHz /4.58 GHz /7.2 GHz with bandwidth of 0.25GHz, 0.57GHz and 0.71GHz respectively. The antenna provides a maximum peak gain of 3.8dBi at 2.52 GHz and provides Omni-directional and bidirectional patterns. The proposed antenna is designed on FR4 substrate having dimensions 41.8 x 28 x 1.6 mm3 and having a loss tangent of 0.02.
