Abstract :
The beam scanning characteristics of a two-element array utilising a ferroelectric phase shifter are presented for the first time. Applying a DC voltage across the ferroelectric material changes the velocity of the input signal, a beam scan of 26° being achieved. The S11 performance and the radiation patterns of the array at two frequencies are presented
