Abstract :
The crosspolarisation performance of reflector antennas fed by a low-crosspolarisation composite feed is investigated experimentally. It is found that an improvement of slightly better than 9 dB can be obtained with this feed, compared with the single-dipole feed. This confirms previously published theoretical findings.
