Amplitude-phase synthesis of an array antenna with radiators composed of three mutually orthogonal electric dipoles

An approach is proposed to solving the synthesis problem for an array antenna whose radiators are composed of three mutually orthogonal symmetric electric dipoles. Each dipole has two controllable inputs, namely, two horizontal dipoles have one common (first) controllable input and the second controllable input is connected to the vertical dipole. It is shown that this configuration allows the implementation of a scanning array antenna with a controlled axial ratio. Numerical examples are presented for the amplitude-phase synthesis of the array antenna with the unit axial ratio in the scan direction.
