| Popis: | A method for calculation of the frequency characteristics of the electromagnetic radiation of waveguide-horn antennas is proposed. The method is based of frequency expansions of the field of the electromagnetic radiation of the antenna excited by auxiliary finite pulses. This radiation is calculated with the use of the method of nonstationary waveguide equations and the concept of a virtual electromagnetic waveguide. Examples of calculation of the amplitude-phase characteristics of the circuit and radiation patterns at fixed frequencies are presented. It is shown that a high accuracy of determination of frequency characteristics is attainable in rather wide frequency band. |
