Design Array Antenna Using Different Feeding Technique in HFSS

Abstract

The Sophisticated wireless communications system requires larger bandwidth, huge gain and nominal size micro strip patch that is able to provide more desirable achievement done with board area of spectrum. Hence, This specification priority to the plan of Micro strip array antennas. In this method nominate the architecture of micro strip array antennas under the corporate feed techniques and series feed techniques for excitation and match the results with series feed and corporate feed technique. Dielectric constant for substrates should be low because of maximum radiation. This micro strip patch array antenna is designed initially by utilizing high frequency structure simulator(HFSS). Patch length and width are determined by utilizing relative permittivity of substrate is 2.2andsubstrate height (h=1.588mm) and centre frequency specification are impedance, returnloss and gain are calculated by using HFSS. The micro strip patch has been intended from 9 to11 GHz.
