Simulation and analysis of a small biconical antenna radiation simulator

This paper aims to build a small biconical antenna simulator with 1/10ns(the rise-time is 1 ns and the half-width is 10 ns) to meet the needs of a scale model experiments. First of all, on the basis of understanding the fundamental theory of biconical antenna, it presents a detailed analysis of the propagation characteristics of the horizontal electric field parallel to the antenna radiated from the biconical antenna, meanwhile, the influences of half-angle, radius, arm length and height on the electric field are discussed. Furthermore, the antenna dimensions are determined as θ
₀
=32°, R=1m, L=7m, H=6m, and the test area of the simulator is calculated according to GJB-8848. The results suggest that the test area is symmetrically distributed with respect to both the X and Y axes.
