Abstract
In this paper, the hexagonal shaped microstrip antennas (MSA) with defected ground plane and gap coupled multi-resonators are proposed and studied for different di-electric constant. The hexagonal shape structure occupies less area and is suitable for compact antenna design. The results showed gradual improvement in impedance bandwidth from 460 MHz to 2.21 GHz with frequency variation from 8 GHz to 7.96 GHz in case of substrate with di-electric constant 4.4. A sudden improvement of impedance bandwidth from 2.19 GHz to 3.75 GHz with frequency variation from 14.32 GHz to 10.5 GHz is observed by just lowering ε r to 2.62.
