Abstract :
A low cost, high performance UHF null steering antenna array has been designed using phase-only weights. The array consists of 8 wide band probe fed E-shaped patch elements on a single substrate layer. Eight-bit digital delay line phase shifters are used to electronically steer one main beam and three nulls within a wide Field Of View (FOV). This paper describes this array´s design, build, and test results which have been shown in good agreement with HFSS computer simulations.
