In this paper, a monopole Ultra-wide band (UWB) textile antenna is designed and analyzed for RF Wireless Energy Harvesting (RFEH). The intended antenna exhibits its excellent characteristics with a compact dimension of 80 60 mm2. In the front plane of the proposed antenna, the microstrip line fed enneagon (nonagon) shaped patch structure has been modified by incorporating rectangular and semi-circular shaped slots. On the other hand, the bottom plane consists of a partial ground plane and a rhombus shaped parasitic radiating structure has been incorporated at the backside of the substrate to utilize the available space above the partial ground to obtain wide impedance bandwidths. Moreover, textile materials are used in this design to improve flexibility and conformability of the designed antenna. From the simulated results, the proposed antenna achieves a wide impedance bandwidth from 1.54 GHz to 12.79 GHz S11 10 dB. Moreover, the maximum gain is 5.03 dB, and the peak radiation efficiency is 95 %. With merit characteristics, the proposed design can be well applied to harvest RF energy. The results show that the proposed miniaturized UWB antenna system can cover the bandwidth requirements of entire UWB systems (3.1-10.6 GHz) and also supports several wireless communication standards such as Wi-Fi (2.4-2.484 GHz, 5.15-5.35 GHz, 5.725-5.825 GHz, 5.925-7.125 GHz), 4G LTE (2.3-2.39 GHz, 2.555-2.655 GHz), Sub 6 GHz 5G FR-1 NR bands (1-6 GHz), and X-band (8-12 GHz). |
