ETRI Journal, Vol. 29, No. 2, Apr. 2007

This cover shows the experimental setup for Fresnel-region measurement on a cylindrical surface. The proposed method enables one to acquire the exact far-field radiation pattern of a relatively large antenna in a small anechoic chamber utilizing a direct far-field measurement system. See page 135.
