An electronically controlled beam focusing/defocusing Phased Array Antenna (PAA) system is proposed for use in Microwave Imaging Relectometry (MIR) systems, which are being developed to measure plasma density fluctuations. The design, construction and performance of a Ka-band 1×8 true time delay E-plane beam scanning and broadening phased array system based on piezoelectric transducer controlled delay line technology using antipodal elliptically-tapered slot antennas are presented. The beam is steered from 21°to +24°and the 3 dB beamwidth is widened by about 10°, the latter being the requirement for the target MIR system.
