Short-pulse characteristics of the conical spiral antenna
Abstract
The short-pulse characteristics of the conical spiral antenna are examined in detail. The antenna is analyzed using a time-domain integral equation. Various peculiarities associated with the numerical solution procedure are discussed, including the effects of a high-Q low-frequency resonance and impedance loading of the antenna. Special attention is directed to the radiated-pulse properties of the antenna for different types of time-varying excitation. Also presented is a quantitative assessment of the antenna's fidelity under pulsed conditions and an approach for obtaining the desired radiated-pulse shape by tailoring the time variation of the applied antenna voltage.
