The sXh900 and sXh2140 expo- sure systems are designed to perform human provocation studies in the GSM and UMTS mobile bands. They are based on patch antennas mounted on the side of the volunteer’s head. The antennas are covered with plastic boxes, such that the two systems are not visually distinguishable.
The setup is able to perform human studies and is based on a low-weight patch antenna that is excited by a fully computer- controlled signal unit. The ant- enna is mounted on a headset which can be worn by subjects in a glasses-like manner (a linkage carries the weight of the head- set).
The system is designed for the exposure of electrosensitive persons at their homes. It is portable (<18kg), can be operated by a tablet computer, and produced incident field strengths up to the guideline limits of ICNIRP for the general public.
