Abstract

In this contribution, the measurement procedure of the impedance and radiation characteristics of a cassegrain reflector antenna is presented. Near-field (NF) measurement techniques have been used to obtain the radiation pattern and the directivity of the antenna. The antenna efficiency has been characterized using a calibrated total power radiometer. Moreover, tolerance effects in the return loss (RL) measurements are discussed, providing a solution to overcome the variability of the input impedance of different antenna prototypes.
