Abstract :
Slot line antennas intended for rnm-wave single beam applications as well as for imaging systems are experimentally investigated. In particular the Vivaldi antenna is investigated, and it is found that a 3 dB beam width of typically 30° is obtained and a 10 dB beam width of about 60° can be achieved. The 10 dB beam efficiency as defined in the text can be made about 60% as compared to 70% for a corrugated scalar horn.
