Abstract

A semi-flexible dual-band antenna at 2.25/5.93 GHz for wearable applications is proposed in this paper. The proposed antenna has dimensions of 19 mm × 12 mm × 0.508 mm and consists of a corrugated monopole with a slit of L-shape inverting at the left side of the monopole and an inductive meander line as a main radiator. Whereas, a strip line of U-shape is attached to a horizontal strip inserted with another inductive meander line on the ground plane. The main radiator and ground plane are used to resonate the higher and lower resonant frequencies at 5.93 GHz and 2.25 GHz, respectively. The corrugations on the monopole result in enhancing the impedance bandwidth of 11.2% (2.19–2.45 GHz) and 2.32% (5.88–6.00 GHz) and reduced Specific Absorption Rate (SAR) of 0.325 W/Kg at the resonant frequency. The proposed wearable antenna is useful for on-body wearable applications for the frequency band of Wi-Fi (2.4–2.45 GHz) in ambient level, ISM band applications, and it is also used as amateur radio and amateur satellite use on a secondary basis. Some portion of the obtained bands is also useful in WLAN applications.
