Abstract

A comb-shaped antenna was designed, optimized and analyzed for an operational frequency of 2.4 GHz. The proposed design was modelled on an RT/Duroid 2880 substrate with dimensions 32 × 28 mm² and 0.8 substrate thickness. The antenna is designed to resonate at 2.4 GHz frequency band on substrate material. The body placement analysis of the proposed antenna was performed using human hand and leg phantom models, and the Specific Absorption Ratio (SAR) was less than 1.6 W/kg (ranging from 0-0.361 W/kg on hand and 0-0.267 W/kg on leg phantoms, respectively). The 3D radiation gains for both hand and leg are 4.95 and 4.81, respectively. Additionally, the vertical and horizontal bending losses were taken at 0˚, 30˚, 45˚, 60˚, respectively and their graphs were analyzed. Owing to its efficient and effective results, this antenna can be utilized for various biomedical applications.
