Определение коэффициента отражения от открытой апертуры биконической антенны и регулярного ТЕМ рупора симметричного типа в частотном и временном представлении методом имитационного моделирования

Abstract

This scientific paper uses the method of Micro-Cap simulation modeling to solve the problem on defining the coefficient of reflection from the open aperture of biconical antenna as a function of frequency and time. For this purpose we used the known equivalent circuit of biconical antenna in the form of a long line loaded at the end with the impedance that depends on the frequency. This known circuit was simplified by taking into consideration the frequency dependence of only imaginary portion of this impedance, which allowed us to simulate the behavior of biconical antenna with the open aperture both as a function of frequency and time. It was suggested to simulate the regular TEM horn of a symmetric type using the equivalent biconical antenna. The coefficient of reflection from the open aperture of TEM horn was determined as a function of frequency and time. It has been shown that the reflection coefficient value determined using the proposed method agrees with known similar data obtained for the frequency representation.
