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 180Â° 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. Â© 2017 IEEE.
A Multi-Band SRR and Strip Loaded Slot Antenna
(Institute of Electrical and Electronics Engineers Inc., 2018) Paul, P.M.; Kandasamy, K.; Sharawi, M.S.
In this paper, a novel compact slot antenna suitable for penta-band applications is proposed. The different resonances are obtained by loading the slot on the top layer with an array of copper strips of equal length and with a Split Ring Resonator (SRR) at the bottom layer. The antenna prototype is fabricated and measured. The simulated and measured results are in good agreement. The antenna is found to resonate at frequencies of 1.51 GHz, 2.35 GHz, 2.9 GHz, 3.66 GHz and 5.6 GHz. Also, a gain higher that 2.4 dBi and a bandwidth of at least 80MHz are obtained for all the bands. Â© 2018 IEEE.
