Design and Analysis of Complementary Split Ring Resonator Based Low Profile Antenna Using Lightweight Polymers for Wireless, Radar and Satellite Communication

Abstract

The article introduces a novel antenna design aimed at addressing the demands of communication technologies. The antenna configuration involves a circular patch coupled with a coplanar waveguide (CPW) and incorporates circular split-ring resonators (SRR) on a Polydimethylsiloxane (PDMS) substrate. The use of PDMS, a flexible and durable material, enhances the antenna's mechanical properties and allows for versatility in various environments. The designed antenna has an overall area of 50x40mm2. The innovative design exhibits resonances at distinct frequencies, specifically 3.3 GHz, 9.7 GHz, and 10.5 GHz, with a return loss of -61.86dB, -31.72dB, -51.81dB, and VSWR of 0.01, 0.5, 0.2 catering to the requirements of wireless communications, radar systems, and satellite applications, respectively. The requirement of the high-end communication module is satisfied by the array configuration resulting in improved directivity and gain. The array module of 2x2 and 4x4 is simulated and analyzed. The choice of the array is selected based on the end application.
