Item A miniaturized quad band hexagon patch antenna for GSM1800, C band and WiMAX applications(2022) Mouhouche, Faiza; Djaf, Kahina; Dehmas, Mokrane; Chibane, Kahina; Ksentini, SafaIn this article, a miniaturized patch antenna using fractal DGS and SRR DMS for GSM1800, C band and WiMAX applications is presented and investigated. Antenna miniaturization and multiband are accomplished by employing a fractal loop on the DGS structure and a split ring resonator slot in the patch. The proposed radiator has a hexagonal shape that operates at 6.8 GHz. To achieve downsize of 20.58, 38.22, 55.14 and 72.75% an antenna is designed using DGS and DMS structures for quad-band application appearing at 1.85, 3.05, 4.2, and 5.4 GHz. Simulated and tested data are investigated. The prototype antenna has adequate advantages, with a simple structure, compact size, multiband, and uniform radiation patterns.Item Quad-band microstrip patch antenna for WLAN/WIMAX/C/X applications(IEEE, 2017) Challal, Mouloud; Mouhouche, Faiza; Djafri, Kahina; Boutejdar, AhmedThis work proposes a novel quad-band microstrip patch antenna for wireless local area network (WLAN), worldwide interoperability for microwave access (WiMAX), C and X applications. It is composed of a modified rectangular patch antenna and two parasitic elements which are both printed on one side of a FR4 substrate, a ground plane on other side on which a U-shaped slot is etched. The proposed antenna, with a total size of 31×33 mm 2 , is fabricated and experimental results illustrate that the -10 dB impedance bandwidth can completely cover the 4.4-4.58 GHz, 5.4-5.6 GHz, 7.2-8.3 GHz and 9.6-10.3 GHz, applications. The simulation results are in good agreement with the measurement ones
