Design and fabrication of new diamond patch antenna for wireless communications

Abstract

The present work investigates the operation performance of a new shape diamond patch microstrip antenna. The proposed diamond antenna covers the bandwidth from 2.3GHz to 18.5GHz that meets the essential requirements of wide band communications applications, and gives gain ranging from -2.6dBi to 5.3dBi. Three slots are of two T-shapes and one S-shape added to diamond patch to improve the gain, therefore the gain becomes in the range from 0dBi to 8dBi. This antenna is fabricated and tested practically and found good agreement between the simulation and measured results.
