Moon Shape Microstrip Patch Antenna with Stair Case Ground

Abstract

In this paper, Moon shape microstrip patch antenna with stair case ground is presented. This antenna provides triple band that can be used for RADAR/SATELLITE/WLAN applications. The antenna is simulated using Ansys Soft HFSS simulator. The size of the antenna is 40mm*45mm*1.5mm.The antenna is printed on FR4 substrate material which has the dielectric loss tangent of 0.02 and the permittivity of 4.4. CPW feeding technique is used to feed this antenna. Stair case ground is used in this design of the antenna to improve its performance. It covers the operating frequency range of 5-10GHz and provides triple frequency bands of 5.78- 5.9GHz, 6.8-7.1GHz and 8.4-8.66GHz. The return losses of -34.3db, -32.3db and -38.4db are provided at the resonant frequencies of 5.8GHz, 7GHz and 8.5GHz respectively by this antenna. Stable omni directional as well as bidirectional radiation pattern is shown by the proposed antenna.
