The design approach of a loop-dipole combined antenna for wearable applications is proposed. In order to mitigate the antenna's performance deterioration caused by the human body, additional loops are incorporated with a wideband dipole. The loops can i) widen the impedance bandwidth by minimizing the reactance of the antenna, ii) increase the antenna's directivity and iii) act as wearable accessories...
Design concept of an implantable, balanced slot-dipole composite antenna is proposed and simulated. The antenna is composed of a tapered slot element and a symmetrical dipole and embedded in a planar stratified phantom. The reflection coefficiency, radiation pattern and gain of the antenna are simulated. It is shown that the antenna can operate at 402–405MHz, 433MHz, 902–928MHz and 2400–2500MHz bands...
