Abstract

The design of the first wearable active receiving textile antenna in the 2.45 GHz ISM band is addressed for use in personal area networks. The integrated low-noise amplifier is realized on a hybrid textile substrate and positioned directly underneath a wearable patch antenna. The antenna and low-noise amplifier are designed by means of circuit/full-wave co-optimization techniques within a novel multi-platform simulation setup to account for all the losses induced by using textile materials. A good agreement between simulations and measurements is obtained. An available gain of about 12 dB, on top of the passive antenna gain of about 5 dBi, and a noise figure of about 1.3 dB are realized. The effect of the human body on the active antenna performance is investigated by means of on-body measurements.
