Abstract
An antenna and method of minimizing capacitive effects of a capacitive body on a loop antenna. The antenna includes a loop antenna, a drive circuit for driving a current through the loop antenna, matching means for matching the impedance of the drive circuit and the loop antenna and a housing for carrying the loop antenna, drive circuit and matching means. The loop antenna is formed from a band of conductive material such that the flat sides of the band are normal to the plane of the loop. The loop antenna is carried by the housing when the housing is carried by a human body with its flat sides normal to the human body and its edges parallel to the human body. The orientation of the loop antenna relative to the human body minimizes the capacitive effect of the human body on the loop antenna and thus decreases the impedance to the flow of current through the loop antenna.
