Circularly Polarized Square Patch Antenna with Trimmed Corners Using Textile Material

Nidhi Sharma, Anjana Goen

In this paper a circularly polarized wearable antenna at 2.4 GHz has been proposed for navigation, military communication, body centric communication and medical emergency. Body centric communication is an important application in the field of wireless communication and since antenna can be implemented on textile material, hence it can be widely used for military communication also. The paper presents the design of the wearable antenna made by the use of jeans substrate textile material with thickness 1mm, dielectric constant 1.7 and loss tangent 0.02. To feed the antenna inset feeding with a quarter wave transformer has been used. The proposed antenna offers approx -20 dB reflection loss, approx 3.5 dB axial ratio and 29% antenna efficiency.
