Abstract
An improved antenna system having a plurality of loop antennas surrounded coaxial shields which have dual electrostatic shield gaps therein. A shunt capacitance is placed across each of the shield gaps. The shunt capacitances are matched and variable among discrete values. Variation of the capacitances provides increased antenna sensitivity without a change in physical dimensions of the antenna.
