Active Tongue Pulsed Transmitting Antenna

A novel, UWB, pulsed, active, and transmitting antenna is proposed, which is based on the authors´ developed and patented UWB antenna design concept called the tongue antenna. This antenna can be directly driven by a pulser circuit with a ferrite ring transformer which contributes to about 30% extra pulse peak amplitude. The active antenna design enables using of different types of pulse shaping diodes driven by 2...1000 V sources. Pulser active elements can be build with low-cost COTS rectifier diodes and its driver with MOSFET switchers that relax to a low-cost pulser design. Other design aspects of the active integrated antenna and pulser are reported including the measured data obtained with its prototype. In particular, derived experimental results include (i) 750 V @ 50 Omega with 2.5-3 ns rise time (P_imp=11 kW); (ii) 500 V @ 10 Omega with 1.7 ns rise time (P_imp=25 kW); (iii) 400 V @ 500 with 1.2ns rise time (P_imp=3.2 kW); (ii) 100V @ 50 Omega with 0.5 ns rise time (P_imp=0.2 kW)
