The Balantenna: An Integrated Impedance Matching Network and Hybrid EMP Simulator
Donald P. McLemore, Gary D. Sower, Carl E. Baum, William D. Prather · 1995
This paper describes the integration of a matching circuit (balun) with the “wormhole” antenna feed concept for a hybrid CW EMP simulator described in previous work [1], The amplifier for this system is still on the ground; however, at the gap of the antenna is a matching network which is designed to give the traditional 1:4 impedance ratio as found in previous designs [2,3,4], With this design, matching for the antenna can be achieved up to the GHz regime.
