Abstract
The design and radiation performance of a modified planar arrangement of concentric circular rings on defected ground plane (DGP) is reported for wireless communication and satellite applications. The etching of a defect in the ground plane is applied for antenna size reduction. The proposed compact antenna is simulated by applying CST Microwave Studio software and fed through strip line feeding. The overall size of the antenna is 39 mm × 46 mm × 1. 59 mm. The antenna resonates at three frequencies and the obtained frequency bandwidth is close to 2.2 GHz (2.330–4.530 GHz). The gain of antenna is simulated in the desired frequency range and is found close to 3 dBi. The proposed arrangement of antenna provides maximum radiations normal to patch geometry and shape of realized radiation patterns is somewhat similar to a dumble shape in the upper hemisphere. This antenna is specifically designed considering the wireless communication systems applicable in India.
