Abstract
This paper describes a textile-based flexible transmitter for wearable applications. The proposed antenna has a cotton substrate and a resonant frequency of 2.45 GHz. Also, the recommended antenna's top patch and bottom ground plane have been created with two separate conducting materials, namely copper and silver shield material. The most essential design considerations for wearable antennas are their portability, gain, bandwidth, flexibility, and body compatibility. Here, the designed antenna is compact with dimensions of 60 × 70 × 2 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup> , Further, the designed antenna exhibits appreciable lower reflection coefficient of −31.05 dB & -35.52 dB for silver shieldit and copper tape conductive materials respectively. Also, the designed antenna has good performance with a gain of 1.492 dBi & -1.281 dBi, bandwidth of 0.11 GHz & 0.1 GHz on and good flexibility. However, it is observed that antenna with copper tape material exhibits better radiation efficiency and gain as compared to antenna using silver shieldit material.
