Design and Evaluation of a Broadband Source Stirring Antenna for Use in a Reverberation Chamber

摘要

A new broad-band antenna structure specifically designed for antenna position stirring in a reverberation chamber is described. The antenna features a reactive rotating source coupler that overcomes the problems of cable and connector reliability and stability often encountered in antenna source stirring due to cable movement. The stirring performance of the new antenna is evaluated by observation of the reduction in Rician K-factor facilitated by the antenna.
