Modeling and Experimental Measurements of a Multiple Beam Digital Phased Antenna Array

The shape of an element for building a phased antenna array (PAA) is optimized via 3D electromagnetic modeling to ensure a relative bandwidth of 9%. Three means of sidelobe suppression for a multibeam PAA are modeled and compared. An experimental model of a digital multibeam phased antenna array is designed. An experimental study of the sample parameters is conducted.
