“…The latter is the Fourier transform of the former (1) If is calculated for a unit complex exciting amplitude at every , then can be considered as the totality of the pulse radiating characteristics (PRC) of an "antenna-free space" system for each point of the space around the antenna [9]. In this case, the radiating antenna transient field for the polarization characterized by the unit vector can be defined as a convolution S (2) where is the antenna input waveform and is the antenna transfer function in the time domain, respectively. We note that the antenna transfer function in the time domain is calculated more simply than in the frequency domain, where, in the best case, the antenna near field can be represented analytically by a series of special functions [10], [11].…”

The article analyzes a flat circular aperture and proposes to use a new analytical expression that describes the radiation pattern of an elementary radiator of an antenna aperture depending on time and integration angle. The formula presented in the paper can be applied to any flat section of the aperture without taking into account its shape. A new equation for the antiderivative function of the impulse response of a circular aperture is presented in the form of an elliptic integral of the second kind. It is shown that the theoretically calculated results are in good agreement with numerical simulations. In the analysis of the numerical model, the method of finite integration in the time domain (FIT) was used. Due to the requirement of a large computational resource, the numerical model was simplified.

“…Aperture antennas allowing us to create a plane wave within the limits of a floodlight beam of the aperture at small distances from the latter hold a special place among the pulsed antennas. Tens of papers are aimed at describing the fields of a circular plane aperture [3][4][5] and a parabolic antenna with a circular aperture [6][7][8]. However, the number of works devoted to calculating the pulsed fields of the more complex-shaped apertures is limited [9].…”
