dc.description.abstractA low-profile multi-frequency leaky wave button antenna for body-centric communications is presented. A leaky wave antenna loaded with U-slots (a combination of U-slots and slits) and tapered slot structures to improve the radiation efficiency, broadside radiation pattern, and widen the steering range is designed. Furthermore, it comprises a whole ground to meet the Specific Absorption Rate standard requirements based on the known standards. The antenna's performances are examined for on and off-body conditions. For demonstration, a prototype is implemented, and the measurement is performed on the chest. The antenna operates at multi bands of 1.7-3.3 GHz (Industrial, Scientific, and Medical and 5G communication) and 4.15-10 GHz (sub-6 GHz and X-band communications). The peak gains of 6.9 and 8.2 dBi were obtained for on and off- body conditions, respectively. Furthermore, the antenna offers maximum radiation efficiencies of 89.3% and 99.3% for on-body and free-space conditions. The specific absorption rate (SAR) values obtained for body-centric communications meet the regulation requirements (e.g., on body tissue at 3.2 GHz, it is 0.78 (1 g) and 0.44 (10 g) W/kg). With an overall miniaturized size, the proposed button antenna could be integrated with clothes. In addition, a multi-wide bandwidth, circularly polarized radiation, a small size, high efficiency and gain, and low SAR values prove that the proposed antenna can be a potential candidate for wireless body area network and simultaneous wireless information and power transfer applications.en_US
