PublicationDual band CPW pentagonal island with modified sierpinski gasket structure at 3.5 GHz and 5.8 GHz(IEEE, 2024-01)
;Amier Hafizun Ab Rashid ;Badrul Hisham Ahmad ;Nornikman Hassan ; ;Mohamad Zoinol Abidin Abd AzizNurzaima MahmodIn this work, a dual-band pentagonal island antenna is proposed for WiMAX 3.5 GHz and WLAN 5.8 GHz applications. Firstly, the basic CPW pentagonal island antenna, Antenna A, is constructed on a 1.6 mm thick FR-4 substrate with a dielectric constant of 4.3 and a copper thickness of 0.035 mm. This antenna contains a pentagonal island with five mini structures of pentagonal island. Then, for Antenna B, a modification is made to the shading made of the Sierpinski gasket structure in the mini structure of the pentagonal island. For simulation Antenna B, it shows the simulation performance of 3.52 GHz and 5.93 GHz with return loss of - 24.84 dB and – 27.94 dB. For the measurement result of Antenna B at desired frequencies of WiMAX 3.5 GHz and WLAN 5.8 GHz, it shows a good performance of – 17.25 dB and – 19.35 dB, respectively. -
PublicationParametric studies of CPW pentagonal Sierpinski gasket fractal patch antenna(Polish Electrical Association, 2023)
;Amier Hafizun Ab Rashid ;Badrul Hisham Ahmad ;Mohamad Zoinol Abidin Abd Aziz ;Nonikman HassanThe parametric study on a dual band CPW Pentagonal Sierpinski gasket fractal patch antenna for WiMAX and WLAN applications is presented in this work. In order to accomplish and advantages of multi-band, broadband, high gain, and low-profile antennas, novel geometries must be developed due to the limits of the conventional antenna design, Sierpinski gasket fractal structure is chosen to improve the antenna performance. The work began with Antenna A as the initiator step with pentagonal patch with CPW technique. Then, it goes with Antenna B was the first iteration stages with pentagonal slot. After that, the work continued by five different parametric studies are chosen in this work to define the effect of different dimensions of the patch antenna. The first and second parametric study works include a different width and length size of the patch antenna at Antenna A. The other three involved in the Antenna B, are including the different dimensions of the CPW/feeding antenna gap, feed line, and lastly the slot width dimension. At 3.5 GHz and 5.8 GHz, the antenna's aimed frequencies are - 31.70 dB and - 22.00 dB, respectively, and these values are feasible for WiMAX and WLAN operation.
