ABSTRACT:
An electronically tunable phased array antenna element compensates for the variation of input impedance as the scan angle of the array changes. A microstrip feed is used which allows monolithic microwave integrated circuits to easily be incorporated in the radiating element housing. The element improves transmit or receive sensitivity. In addition, this electronic tuning will counteract detuning of the element caused by external influences such as electromagnetic field coupling from other nearby antennas.
