Abstract

A mathematical model of a spherical antenna excited by a slot cut in an impedance endwall of a semi-infinite rectangular waveguide was built using a rigorous solution of the problem. Control of energy characteristics is accomplished by changing impedance distributed on the end-wall of the waveguide section. If the waveguide is excited by the wave H₁₀, the wavelength tuning reaches (30-35)%, i.e. about a half of the wavelength range of single mode waveguide regime.
