Abstract
This paper presents a preliminary design of a textile antenna using aperturecoupled technique for Global Positioning System (GPS) application. Mostly used in wearable application, textile materials are suitable to be applied as the antenna substrates due to the flexibility and conformability characteristic. In this paper, felt material with the relative permittivity, Er1 of 0.76 and thickness of 2.69 mm is chosen as the substrate, and is attached to a pure copper layer as the conductive material with the thickness of 0.07 mm. Meanwhile, the textile material used as the feed substrate is fleece with the thickness of 0.69 mm with the relative permittivity Er2 of 0.91. The design procedure is discussed and the simulated data using the CST Microwave Studio software is further analysed in terms of the return loss, gain, directivity and radiation pattern.
