Abstract

Abstract

In this paper, we introduce a ultra-wideband curving TEM horn, the considerations in product design are mainly power capacity and caliber match. Comparing the ultra-wideband curving TEM horn with the classical invariational-impedance TEM horn, the main structure improvements are coaxial-to-plane converter and curving radiation-plate. The input and radiation characteristics of this two antennas are analyzed. Results are as follows: when the antenna is excited by Gaussian pulse with a pulse width of 960ps, the peak-power transmission efficiency of the coaxial-to-plane converter is 85%. Compared with the invariational-impedance TEM horn, the curving TEM horn has 30% increase at peak-peak electric field radiation, its H-plane directivity diagram is compressed from 80 to 60, furthermore, the transmission and radiation characteristics are improved within 700 MHz, the transient peak-power-capability of the pulse reaches 15 GW. This curving TEM horn is used successfully in the high-power-microwave radiation system of ultra-wideband.
