Abstract

Gain and phase of a ridge waveguide antenna have been determined in the boresight direction for frequencies in the range 2-18 GHz. The measurement procedure used to determine the antenna characteristics is a variant of the three-antenna method. The content of the report is divided into three sections. In the first section we define antenna concepts, derive some relations and summarize the results of the measurements. In section two the measurement procedure and its error sources are described. The third section consists of five appendices containing derivations to relations in the report.
