Abstract
A body coupled antenna system usable in a personal locator unit includes an antenna element for connection to an RF circuit; a coupling plate for conductively coupling to an adjacent body for broadening the tuning frequency and reducing the loading sensitivity; a first capacitance interconnected between the coupling plate and the antenna element; and a second capacitance interconnected between the coupling plate and the RF circuit; the first and second capacitances being set to restore a predetermined matching impedance level while maintaining the broadened tuning frequency.
