Phase characterization of 1–200 MHz RF signal coupling with human body

A novel substrate integrated waveguide (SIW) slot antenna array is proposed in this paper. The array, based on SIW scheme, consists of one compact SIW 4-way power divider and 4 radiating SIWs each supporting 4 radiating slots. The 4-way power divider uses the self-compensating phase shift technique, which can make the feeding network operate over a broadband. Comparing with conventional SIW slot antenna arrays, this array has simple structure and broadband bandwidth. The antenna array is fabricated and the measured results are in agreement with the simulated ones. A relative bandwidth over 10% is achieved with return loss below 10 dB.
