Item SRR loaded slot antenna for multiband applications(Institute of Electrical and Electronics Engineers Inc., 2017) Paul, P.M.; Kandasamy, K.; Sharawi, M.S.A compact square shaped microstrip triband slot antenna is proposed. Two Split Ring Resonators (SRR) of the same configuration are loaded at one edge of the slot in a back to back orientation. The other edge of the slot is displaced with two 180° rotated SRR's with multiple slits. The additional bands are obtained from the resonance properties of the loaded SRR's. The antenna is simulated and measured. The resonance frequencies obtained are 2.7 GHz, 4.3 GHz and 4.7 GHz. A minimum bandwidth of 130 MHz is achieved. © 2017 IEEE.Item Quad band SRR loaded square slot antenna(Institute of Electrical and Electronics Engineers Inc., 2018) Paul, P.M.; Kandasamy, K.; Sharawi, M.This paper proposes a Split Ring Resonator (SRR) loaded quad band microstrip slot antenna designed to operate at 2.42 GHz, 4.33 GHz, 8.46 GHz and 10.9 GHz. The additional resonant bands are generated by loading the square slot antenna with two pairs of SRR structures on either side of the feed line. The bands centered at 8.46 GHz and 10.9 GHz are found to exhibit wideband and circular polarization properties respectively. The resonance band at 8.46 GHz provides a wide bandwidth of 2.43 GHz. One pair of the loaded SRR structure consists of two spiral shaped connected SRR's. The excitation of these structures gives rise to a circularly polarized band at 10.9 GHz with 3-dB axial ratio bandwidth of 390 MHz. Maximum gains of 3.82 dB, 3.95 dB, 7.5 dB and 4.2 dB are obtained at the four resonant frequencies, respectively. A minimum bandwidth of 270MHz is observed for all the bands of operation. © 2017 IEEE.
