To achieve high-performance in a simple way, the loop calibrator concept is applied to a receiver array at Ka-band. Non-directive stripline couplers are used to feed calibration signals into each receiver channel through capacitive coupling. A three-antenna array is built and characterized to validate the calibration concept. Errors caused by imperfections of the calibration system are analyzed in time domain signal pattern.enLoop calibrator for DBF receiver array at Ka-bandConference PaperOther
