Abstract
Direction control of continuous wave (CW) beams in phased array antennas is investigated in this work using Monolithic Microwave Integrated Circuit (MMIC) quadrature modulator control. The concept was simulated using Matlab and Agilent’s ADS and then implemented using off-the-shelf quadrature modulators, more usually used in the signal chain for digital communications. These components were used as they have been optimised to smoothly and accurately modify the phase of a local oscillator input, for subsequent transmission as a modulated communications carrier, which is similar to the beam steering requirements of a phased array antenna. The phase controlled signals fed four simple patch antennas and the subsequent beam control characterised and presented here.
