CROSS-REFERENCE TO RELATED APPLICATION
This application is related to U.S. application Ser. No. 11/867,046, filed 4 Oct. 2007, entitled "Multi-band Current Probe Fed Antenna" (Navy Case # 84943), which is incorporated by reference herein in its entirety for its teachings.
BACKGROUND OF THE INVENTION
With increasing numbers of wireless communications systems available today, more and more antennas are required to support them. In many situations the available real estate for placement of antennas is limited. For example, the area available
on building rooftops, and exterior surfaces of automobiles, aircraft, and sea craft, which often serve as antenna placement locations, is particularly limited, especially in scenarios where multiple antennas are desired. A need exists for an antenna
with a relatively small footprint.
BRIEF DESCRIPTION OF THE DRAWINGS
Throughout the several views, like elements are referenced using like references.

I claim:
1. An antenna comprising: a first current probe having an aperture; a pump having a nozzle, wherein the pump is configured to pump a free-standing stream of electrolytic fluid out the
nozzle and through the aperture; a first transceiver operatively coupled to the current probe; a pressure regulator operatively coupled to the pump, wherein the pressure regulator is configured to alter the pressure of the electrolytic fluid between
the pump and the nozzle, wherein the first current probe is positioned approximately where the electrolytic fluid exits the nozzle, and wherein the nozzle is comprised of multiple heads such that the stream of electrolytic fluid is comprised of multiple
sub-streams; second and third current probes, wherein the second and third current probes each have an aperture, and wherein the apertures of each current probe are approximately aligned with each other; and second and third transceivers, wherein the
second and third transceivers are oper . . . . More |
