CALCULATION OF THE VOLTAGE FUNCTION IN CURVILINEAR SLOT ANTENNAS
This paper considers the problems of calculation of the voltage function of slot antennas placed on cylindrical surfaces. The calculations were carried out assuming that the investigated antenna is excited by discrete points with integrated alternating currents by a system of cylindrical strip lines. Excitation of linear transverse slot line on the cylinder was conducted in-phase and equal-amplitude. This leads to a blurring the voltage function at length compared with the analogous problem for a slot in flat screen. If the ring slot is excited in-phase and equal-amplitude in four points symmetrically distributed on the surface of cylinder there takes place the rectification of voltage compared with the same slot in the flat screen. Therefore, to achieve the same uniformity of voltage function, it requires fewer excitating lines. The simulation results show that the calculation of voltage function for the slot antennas placed on a cylindrical surface using the method by Ya.N. Feld gives more accurate results compared to traditional methods.
