Multi-Forked Microstrip Patch Antenna for Broadband Application

Abstract

In this paper, a new design simulation of multi-forked microstrip patch antenna is presented. The proposed antenna design consists of rectangular patch structure loaded multi-slotted forked as a novel shaped of the patch, with Arlon AD320A (tm) dielectric. The coaxial probe feed technique and microstrip edge feed are used as a direct feed. The composite effect of integrating these multi-shapes forked patches techniques introducing the new multi-slotted patch. The best results of the proposed antennas were a wide impedance bandwidth which is 114% at 10.31 GHz resonance frequency for the microstrip line feed approach and maximum achievable gain is 6.3 dB for the coaxial probe feed approach. The simulated results of return loss, radiation patterns, and voltage standing wave ratio are obtained by using the finite element HFSS 13.0 software.
