Measurement and implementation of antenna radiation pattern
Chirag Gupta, Divyanshu Singh, Nitin Garg
In a recent paper, a nascent technique that allows to perform actual antenna radiation pattern measurements in reverberation chamber (RC) has been presented and then the radiation pattern are used to form 3D radiation pattern of the horn antenna. In this contribution, an improvement of this technique is presented; an antenna radiation pattern is obtained by performing only one measurement per angle under study, taking advantage of real-time Doppler Effect. In order to display the validity of this improved technique, the radiation pattern for both E- and H- planes of a horn antenna is measured in an RC, the results obtained in are matching with the result obtained in AC and the values provided by the antenna manufacturer, respectively. Furthermore, these radiation patterns are used with various approximations to demonstrate the antenna radiation pattern in 3D using MATLAB.
