Patent ID: 8228232

Claim:
A phased array antenna in communication with as radiating element, the phased array antenna comprising: a 90° hybrid configured to receive dual linearly polarized RF signals from the radiating element, wherein the 90° hybrid is configured to inject a 90° phase shift and generate a RHCP intermediate signal and a LHCP intermediate signal; a first vector generator configured to receive the RHCP intermediate signal, wherein the first vector generator is configured to phase adjust the RHCP intermediate signal for beam steering and output a first RF signal; and a second vector generator configured to receive the LHCP intermediate signal, wherein the second vector generator is configured to phase adjust the LHCP intermediate signal for beam steering and output a second RF signal; wherein the first vector generator and the second vector generated individually comprise a first quadrant select in parallel with a second quadrant select and a first variable gain amplifier in parallel with a second variable gain amplifier.
