ABSTRACT:
An antenna system comprises at least first and second antennas circumscribing a common center thereof at respective different distances from the common center, and circuitry for exciting the first antenna at a greater level than the second antenna, the excitation of the first and second antennas by such exciting circuitry being of respective opposite phasing. The excitation circuitry is operative to provide first fields adjacent the antenna system to a predetermined distance therefrom which are essentially controlled by the excitation of the first antenna and to provide for second fields beyond the predetermined distance which are of lesser strength than the first fields and are determined by both of the first and second antennas.
