dc.description.abstractThis thesis presents the design, simulation, and analysis of two wearable monopole antennas developed on a jeans textile substrate for wireless communication applications. The work is divided into two main designs, each targeting different frequency bands. The first design is a wideband antenna operating from 3.75 GHz to 5.85 GHz, covering sub-6 GHz, WLAN, and ISM bands, using a modified T-shaped patch with a partial ground plane and circular DGS slots. It was fabricated and tested, achieving a peak gain of 4.6 dBi and efficiency above 80%.The second design is a compact triple-band antenna resonating at 4.15 GHz, 7.53 GHz, and 10.68 GHz, covering C-band, X-band, and Ku-band, using a symmetrical loop-loaded structure with a comb-shaped DGS. It achieved a peak gain of 6.6 dBi and efficiency above 80% across all bands. Both antennas were designed and simulated using ANSYS HFSS and evaluated in terms of reflection coefficient, gain, efficiency, radiation pattern, and surface current distribution. The first antenna was also experimentally validated. The results confirm that jeans textile substrate is a suitable choice for wearable wideband and multiband wireless communication applications.
