A novel phased array based on the extended resonance power dividing technique

A novel phased array based on the extended resonance power dividing technique has been presented. This phased array eliminates the need for a separate power splitter and phase shifters in a conventional phased array system. As a proof of principle, a 2 GHz extended resonance based phased array consisting of 4 microstrip patch antennas has been designed, fabricated and tested. The measured scan range was +/- 13.5 degrees with an average beamwidth of 26 degrees.
