Item 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. © 2018 IEEE.Item A Copper Strip Array Loaded Multiband Square Slot Antenna(Institute of Electrical and Electronics Engineers Inc., 2020) Paul, P.; Kandasamy, K.; Sharawi, M.S.A simple copper strip array loaded multiband square slot antenna with microstrip line feed is proposed in this paper. The slot antenna is designed to radiate at 2.28 GHz. The slot is loaded with a uniform array of rectangular copper strips to produce other resonances at 2.2 GHz, 3.4 GHz, 4.6 GHz, 5.4 GHz, 6.6 GHz. The proposed antenna is modeled and simulated using HFSS. The antenna prototypes are fabricated and tested. Good agreement is obtained between the measured and simulated results. The surface current distributions at the various resonant frequencies are simulated. The principle of operation is explained based on the distributions obtained and using analytic equations. An equivalent circuit model is also studied. Impedance bandwidths of 500 MHz, 300 MHz, 600 MHz, 400 MHz, 600 MHz and a gain of above 3 dB is obtained at the five resonant frequencies. © 2020 EurAAP.
