Leaf-Shaped Textile Dipole Antenna Design

Abstract

Textile dipole antenna with a leaf-shaped operating frequency at 2.4 GHz has been designed, fabricated and analyzed. The effect of the conductive threads on the leaf-shaped antenna is investigated. The leaf-shaped antenna is stitched around the edge of the antenna and the performances of the leaf-shaped textile dipole with and without conductive thread is evaluated. From the measurement of return loss, the leaf-shaped dipole antenna with the round stitch shows better performances with the optimum resonances compared with the antenna without the conductive thread. The measured results confirm that with the round stitch contributes optimum performances to the leaf-shaped dipole antenna.
