Method for reducing reflection of multi-feed source reverberation chamber antenna

A method for reducing reflection of a multi-feed-source reverberation chamber antenna comprises the steps that a reverberation chamber is emptied, and a reverberation chamber testing system is built; measuring an S parameter between transmitting and receiving antennas of the reverberation room test...

description A method for reducing reflection of a multi-feed-source reverberation chamber antenna comprises the steps that a reverberation chamber is emptied, and a reverberation chamber testing system is built; measuring an S parameter between transmitting and receiving antennas of the reverberation room test system to obtain a reflection coefficient of the transmitting antenna; the signal source emits a signal, and the field intensity in the reverberation chamber is measured; comparing the actually measured field intensity in the reverberation chamber with the target test field intensity; if the actually measured field intensity in the reverberation chamber is lower than the target test field intensity, adding a transmitting antenna, and improving the actually measured field intensity in the reverberation chamber by using a multi-feed source reverberation chamber technology; the transmitting antenna is connected with the transmitting link through the power divider; according to the invention, while the multi-stage feed
