waveguide radiating element and system for measuring the performance of an antenna using such a radiating element.

摘要

Waveguide radiating element (500) having a working frequency that is tunable below the cut-off frequency, the waveguide comprising a rectangular tube (550) presenting a longitudinal axis (530) and a rectangular mouth on a plane perpendicular to the longitudinal axis, the rectangular mouth comprising an upper and a lower edge, as well as lateral edges, the tube being partially filled with a MNG meta-material.
