Abstract
In this paper, we have proposed a Slotted Microstrip Patch Antenna with a Defected Ground Structure (DGS). Here, we have integrated the concept of DGS and Slotted Patch Antenna in order to get enhanced bandwidth and gain. The proposed antenna consists of a microstrip fed slotted rectangular patch with E-shaped cut in the ground plane. The performance of this antenna is discussed and analyzed with the variations in patch width and number of slots. The variations in Return Loss (S11), Radiation Pattern and Gain of the designed antenna are analyzed for different case studies. The antenna shows a dual band characteristics having a return loss of below −20 dB at 3.2–3.5 GHz and below −10 dB at 5.6–5.8 GHz, which is suitable for IEEE 802.16 WiMAX and IEEE11p WLAN applications. CST MWS 2015 is used to simulate the antenna structure.
