Radiation of the dielectric wedge antenna into air has been analyzed. Originally developed and built for radiation into ground, the antenna has demonstrated good performance in free space. A modification of the antenna, which possesses flat gain over a frequency band from 1 GHz,

New facilities for time-domain antenna measurements have been developed.Specific features of these facilities are: antenna measurements bandwidth from 1GHz till 26GHz, short measurement time due to the pulse repetition rate of 10MHz and high stability of the time and magnitude ax

The Dielectric Wedge Antenna has been modified for radiation in free space. While the original antenna has been developed and built for radiation into the ground at low frequencies, the modified antenna has been designed for modified for radiation of ultra-short pulses with spect
