Abstract

This paper presents a lightweight and simple structure of slotted circularly polarized (CP) patch antenna using conductive textile. ShieldIt Super is used as a conductive textile and felt is used as a substrate of the antenna. The prototype is designed with a total dimension of 36 mm x 36 mm and spaced by a 3 mm thick felt fabric for Body-centric Wireless Communication (BCWC) operating in the 5.2 GHz Industrial, Scientific and Medical (ISM) Hyper Local Area Network (LAN) band. A parametric study has been carried out in order to investigate the antenna basic characteristics, thereby enhancing the antenna performance. The proposed antenna is benchmarked against the without slot circularly polarized textile patch antenna. The measured results show that the slotted CP patch textile antenna produces better performance compared to the without the slot CP patch textile in terms of bandwidth with an acceptable 3-dB axial ratio bandwidth and gain.
