Reduction of Amplitude and Duration of Post-Pulse Oscillations in Bow Tie Active Radiating Antenna
Abstract
The paper investigates one of the ways of suppressing post-pulse oscillations in ultra-wideband (UWB) electromagnetic pulses radiated by a bow-tie type antenna excited in active mode (the pulse generator is located directly on the radiator). Since this excitation method does not require balancing or other elements that match the impedances, conditions are created for increasing the radiated power with the same power consumption. To suppress post-pulse oscillations in the radiated field, resistive elements with high resistance are used. They are located near the excitation region in order to absorb the non-radiated part of the excitation signal energy accumulated in the antenna. The influence of the antenna form factor and load resistance on the shape of the radiated signal is experimentally analyzed.
