The propagation properties of large size TEM antennas are experimentally studied. The size of the TEM antennas is 60 m20 m10 m and the character impedance is 120 . A kind of dielectric foil switch is designed compactly with TEM antennas which can generate a double exponential waveform with an altitude of 10 kV and a rise time of 1.2 ns. The radiated field distribution is measured. The relationship between the rise time/altitude and the distance is provided, and the propagation properties of large size TEM antennas are summarized. The results show that the rise time along the transmission distance increases. The transmission distance is 50 m and the rise time increases about 1.2 ns. An exponential decay trend of electric field amplitude with the transmission distance. This work is valuable for the design of large size guided wave simulator.
