Has any one used a voltage controlled phase shifter in the measurements of phased arrays? i need some help in clearing some ambiguities regarding the use of voltage controlled phase shifters in phased array radiation pattern measurements. Your response will be highly appreciated.
I have done a little, but not necessarily for the measurement, but for adaptive radiation pattern. Maybe this is of interest: https://www.researchgate.net/publication/282008718_Analog_and_Digital_Nulling_Techniques_for_Multi-Element_Antennas_in_GNSS_Receivers

Semiconductor phase shifters, based primarily on GaAs, but also on SiGe and InP, have enjoyed steady progress for the past two decades. Their small size and relatively low power consumption compared to ferrite devices has created new insertion opportunities. Many possible circuit topologies, using diode or FET switches in various configurations, exist.
