Abstract :
The effect of amplitude and phase errors on the radiation properties of phased array can be reduced by using a proper calibration scheme. Based on a brief review of microwave phased-arrays we derived the key requirements for a new anechoic millimeter-wave (mm-wave) antenna set-up which was constructed. The residual measurement errors obtained with this new set-up are low enough for the calibration of low-sidelobe mm-wave phased arrays.
