A Novel Circular Slotted Microstrip-Fed Patch Antenna with Three Triangle Shaped Defected Ground Structure for Multiband Applications
Objective
Propose a novel circular slotted rectangular patch antenna with three triangle-shaped defected ground structures for wideband applications.
Abstract
In this a novel circular slotted rectangular patch antenna with three triangle shaped defected ground structure (DGS) has been proposed. In this work, an antenna of size 38 × 25 mm2 is presented. To make the radiating patch, the circular slots of radius 3 mm have been cut from the three sides, i.e., left, right, and upper, and also from the center of the conventional rectangular patch. Three triangle shaped defects have been etched from the ground plane. Optimization has also been performed on the designed antenna to have higher bandwidth, lower return loss, and better impedance matching. Three impedance bandwidths of 0.957 GHz, 0.779 GHz, and 0.665 GHz with resonant frequencies at 3.33 GHz, 6.97 GHz, and 8.59 GHz, respectively have been obtained. For the testing of proposed antenna, a prototype has been fabricated. It is observed that the results obtained with simulated and fabricated antennas are comparable. The proposed antenna design can be used for wireless and future 5G applications.
