Abstract

This paper describes the challenges that arise in active wearable textile antenna design and optimization. After a short introduction, design strategies for two cases with different needs are discussed and examples are given for each design strategy. In the first case, a low-noise amplifier is connected directly to a 2.45 GHz ISM-band antenna by optimizing the antenna impedance to match the low-noise amplifier input impedance for optimal noise performance. In the second case, an aperture-coupled GPS antenna incorporating a discrete 50 Ω hybrid coupler is linked to a low-noise amplifier by means of a matching network to match the 50 Ω hybrid coupler port to the low-noise amplifier impedance for optimal noise performance.
