摘要: The ability to switch between propagating modes is important for body-centric applications such as medical body area networks where a single node may need be able optimise communications either on-body sensor links or off-body the wider network. Therefore, we present compact 2.45 GHz active mode-switching wearable antenna both and wireless communications. single-layer patch was pattern-switched using shorting pins had an impedance bandwidth of 253 MHz 217 radiating modes, respectively. An efficiency 57 % 56.8 obtained mode respectively when placed in close proximity phantom that represents muscle issue at GHz.
