On-body propagation characterization with an H-plane Substrate Integrated Waveguide (SIW) horn antenna at 60 GHz

A planar end-fire H-plane Substrate Integrated Waveguide (SIW) horn antenna is designed for 60 GHz on-body channel measurements. The proposed antenna radiates with a polarization normal to the human skin, and yet exhibits a low profile. Furthermore, a 6.1 GHz bandwidth (S11 < −10dB) is achieved, which enables wide-band channel characterization. The antenna has been fabricated and its performance is evaluated in the presence of a skin-equivalent phantom. Its suitability to perform on-body channel measurements is then discussed.
