ABSTRACT:
An antenna for use in measuring current induced in a human body from exposure to radio frequency, electromagnetic fields approximates the impedance the human body over a wide frequency band of operation. The antenna includes an elongated resistive strip secured to a rigid supporting member, the supporting member and resistive strip being mounted on a supporting base plate. The antenna obviates the need for a human subject to be exposed to electromagnetic fields which need to be assessed to determine whether the induced current exceeds permissible guidelines. The antenna is collapsible so that it is easily transported to any desired location.
