Originální abstrakt

In this paper, we describe the design and simulation of on-body antenna for wireless body area network (WBAN) communication operating in the 61 GHz ISM frequency band. We developed a disc-like concept of an antenna. Instead of a direct connection between a circular disc and a feeding pin, the electromagnetic coupling is used. This concept enables us to obtain relatively broadband characteristics with omnidirectional radiation pattern and vertical polarization suitable for on-body communication. Impedance properties and radiation of the antenna were studied in open space and on a tissue-equivalent phantom representing the human body. Fabricated prototype is well matched from 59.3 GHz to 63.4 GHz. The bandwidth of the antenna is about 7%. Antenna analyzed close to body tissue exhibits efficiency at least 25 % and the maximum gain 5.2 dB in horizontal plane.
