Design and Analysis of Frequency Reconfigurable Antenna Loaded Complimentary Split Ring Resonator for Wireless Applications

Abstract

This paper presents a multi-band reconfigurable antenna, circular patch antenna loaded with combination of rectangular and infinity shape complementary split ring resonator (CSRR). Four slots used for connecting the rectangular with infinity CSRR, where the four PIN diodes loaded in order to achieve reconfigurability. The circular patch has printed in Roger RT/5880 substrate having a dielectric constant of 2.2 within a size 37.35x34.35x1.57. Extraction of permittivity negative of the CSRR is discussed in detail. The proposed antenna can be used in modern and mobile communication devices.
