Antenna
Abstract
Various investigations of antenna design and operation are presented. The design of phased annular antenna arrays of interacting radiators excited by a Butler circuit is discussed. The critical wave number and wave resistance of a coaxial line with a cross-shaped interior conductor are determined. In addition, the synthesis of difference direction patterns of spherical antennas is examined and the input resistance of a vibrator with a dielectric cover is calculated by the induced EMF method. Finally, the calculation of the H-plane stepped joint of rectangular waveguides is discussed.
