Analysis of circular polarization textile antenna in bending condition

Abstract

A circular polarization (CP) textile antenna is designed for Global Positioning System (GPS) application. The truncated rectangular patch antenna is has a full ground plane from Shieldit Super and felt fabric as a substrate. The proposed antenna operates at 1.575 GHz with a good bandwidth from 1.540 to 1.625 GHz. The optimized chamfer has been made at two edges of a rectangular patch in order to produce a Left Hand Circular Polarization (LHCP) with a good axial ratio (AR) badwidth of 1.569 to 1.589 GHz. This manuscript also presents the analytical performances of CP textile antenna under bending condition that suitable for the on-body antenna applications.
