Patent ID: 7737906

Claim:
An Electronically Steered Phased Array Blade Antenna Assembly comprising: a pair of dipole antenna elements spaced apart from one another by a preset distance, wherein the pair of dipole antenna elements includes two symmetrical antenna blades with each of the antenna blades having a fan out angle of approximately 45 degrees; a 90 degree hybrid coupler having a pair of input radio frequency (RF) ports and a pair of RF output ports wherein one of the pair of input RF ports is connected to a dummy load, and a remaining input RF port is connected to an RF source; an electronically controlled RF switching device having a switching command input port for receiving a switching command, a pair of RF input ports and a pair of RF output ports, wherein the pair of RF input ports of the electronically controlled radio frequency RF switching device receives the RF source from the RF output ports of the 90 degree hybrid coupler and the second pair of output ports of the electronically controlled RF switching device are connected to the pair of dipole antenna elements; a pair of coiled RF feed lines connecting the pair of dipole antenna elements to the pair of RF output ports of the electronically controlled RF switching device, wherein each of the pair of coiled RF feed lines operates as a balun; and said pair of dipole antenna elements, said electronically controlled RF switching device and said pair of coiled RF feed lines being rigidly mounted to a dielectric substrate, wherein a plurality of clamps are mounted on the dielectric substrate at selected points to achieve structural stability when the electronically steered phased array blade antenna assembly is attached to and positioned within a radome.
