Abstract
In this paper, a microstrip feeding rectangular MPA using DGS structure into ground plane is presented. In the absence of a slot, a conventional rectangular MPA is also considered for confirming the validity of designed antenna. This conventional antenna design was found to resonate on 7.0611 GHz frequency at −23.70 dB return loss. When introducing the combination of two L-shaped DGS structures into the ground plane, then the frequency shift from 7.0611 GHz to 3.2012 GHz is observed. The main involvement of this antenna design is the multiband responses. Further, the end result confirms that the designed DGS antenna has return loss at −14.0170 dB on 3.2012 GHz, −16.5623 dB on 4.4505 GHz, −17.8874 dB on 5.1952 GHz, and−17.5474 dB on 8.9349 GHz.
