A wearable, small, and effective antenna that incorporates artificial magnetic conductor (AMC) is suggested. In addition to the band notches used as the front end and the square and circular ring array pattern used as the back end, the rectangular monopole patch antenna's inclusion of slots as well as bevels/cuts creates a wide bandwidth. The middle paper serves as an isolator to prevent interference between the AMC's ends. The AMC Meta surface that supports the specified antenna reduces a Specific Absorption Ratio (SAR) considerably and transforms its bidirectional radiation pattern into a unidirectional one. The proposed antenna is outside its Ultra-Wideband (UWB) region of 3.1 through 10.6 GHz, with a frequency range of 3.8 to 13.3 GHz. Band notches have been cut out of the emitting patch using slots within the sub-bands spanning 5.8 through 6.2 GHz along with 6.6 to 9.1 GHz. The overall dimensions of the building are 29 x 28 x 3.624 mm2. The AMC layer greatly enhanced this antenna's transmission effectiveness. We used the paper material to produce the suggested antenna compatible with WBAN purposes because it is a flexible and affordable substrate. This offered antenna serves as a suitable option for a range of UWB wearable body area network (WBAN) devices because of its simple structure, thin profile, minimal SAR, wide operational bands, as well as several band notches. |
