Wearable technologies are increasingly popular, prompting a rise in wearable antenna usage, especially in wireless body area networks (WBAN). However, constructing antennas for wearable is challenging due to the presence of the human body. Factors such as flexibility, precision, and size are crucial considerations. Researchers are actively working on these challenges and have made significant progress in the field. This work presents a compact wideband (WB), low profile and low-cost antenna, which is suitable for wearable biomedical telemetry applications. The antenna is designed using FR4_epoxy dielectric material having dimensions of 0.440  0.440  0.0280 mm³. Two rectangular slots are engraved on the patch to improve the impedance bandwidth and gain. The proposed slotted wearable antenna achieved an impedance bandwidth of 2.26 GHz (3.58 – 5.84 GHz) with a center frequency at 5.3 GHz and high gain of 5.9 dBi. This antenna presents a solution for wearable biomedical telemetry, offering compact size, high performance, and adaptability to various conditions. The simulation results of return loss, voltage standing wave ratio (VSWR,),impedance matching, gain and radiation pattern of the proposed antenna are obtained through Ansys 2021 R2 high frequency structure simulator(HFSS) software.
