Investigations on metamaterial slot antenna for wireless applications

Abstract

This paper represents a Circular Complementary Split Ring Resonator (CCSRR) which produces an S band (i.e. 2GHz-4GHz) and X band (i.e. 8GHz-12GHz) frequencies and can be useful for various applications, which is evolved in the third iteration. In which first iteration was Circular ring monopole (CRM) and later a complementary split ring was introduced in the ring mono pole. The overall proposed antenna dimensions are (40mm X 34.8mm X 1.6mm) and fabricated on FR-4 substrate. Antenna with dual (high and low) bands resonant frequencies were proposed and designed by using circular ring monopole which was extended to split ring resonator yields a high gain when compared to previous designs. Proposed model Circular Complementary Split Ring Resonator (CCSRR) works in 3.7GHz for S-band applications like Wi-MAX and 8 GHz for X band applications like terrestrial communication with a gain of 12.1 dB. The proposed antenna was designed and simulated in HFSS software and results were plotted with help of origin pro software.
