Peak gain and directivity estimation accuracy from pattern measurement

This paper provides a comparison between different near-field measurement techniques for antenna gain and directivity estimations. Several gain measurement techniques exist including comparison gain and direct gain, which have their own advantages and disadvantages in terms of accuracy, cost and measurement time. In this study, the comparison gain technique is used. In addition, three different near-field measurement methods including planar, cylindrical and spherical have been compared for antenna gain and directivity estimation.
