An ultra-wideband time-domain antenna

The theory of the transient electric-field pulses testing receives extensive attention in the fields of national defense and industry. How to measure the transient electric-field pulses efficiently and accurately is an urgent problem to be solved in electromagnetic countermeasures. Ultra-wideband time-domain antennas are the core component of the transient electric-field measurement systems. In this paper, an ultra-wideband time-domain antenna is proposed to measure the transient electric-field pluses. The proposed antenna is based on progressive conical dipole structure, which couples electric-field energy through a pair of differential dipoles. The simulation and measurement results show that the proposed antenna has excellent differential characteristics in the frequency range of 10MHz~1GHz. The proposed antenna has advantages of wide operation frequency, small size, simple processing and low cost.
