Abstract: A slot antenna for receiving and/or transmitting a RF signal at a desired one of a plurality of different frequencies. The slot antenna includes at least one conductive sheet having a slot defined therein, the slot being longer than it is wide and having at least one end which is open. A plurality of switch members are mounted along said slot close to the open end thereof, each of said plurality of switch members acting, when closed, to couple the at least one conductive sheet on one side of said slot to the at least one conductive sheet on a second side thereof. A feed point is provided for adjacent said slot. The plurality of switch members are closable in a controlled manner to change a desired resonance frequency at which the slot antenna receives and/or transmits the RF signal.

Abstract: Disclosed is an antenna system including a Luneberg Lens having a spherically shaped outer surface and a spherically shaped focal surface spaced from its outer surface with a plurality of patch antenna elements disposed along the focal surface of the Luneberg Lens; and a power combiner for combining signals received by said plurality of patch antenna elements. The disclosed antenna system may be used a part of a robust GPS system having a plurality of GPS satellites each transmitting a GPS signal; a plurality of airborne GPS platforms, each GPS platform including a GPS transmitter for transmitting its own GPS signal, the GPS signals being transmitted from the plurality of airborne GPS platforms being differentiated from the GPS signals transmitted by visible GPS satellites; and at least one terrestrially located GPS receiver for receiving the GPS signals transmitted by visible ones of the GPS satellites and by visible ones of said airborne GPS platforms.

Abstract: An antenna having at least one main element and a plurality of parasitic elements. At least some of the elements have coupling elements or devices associated with them, the coupling elements or devices being tunable to thereby control the degree of coupling between adjacent elements. Controlling the degree of coupling allows a lobe associated with the antenna to be steered.
