Abstract

Waveguide power dividers capable of splitting a dual-mode electromagnetic signal into at least two output signals with differing amounts of horizontal and vertical polarization states are disclosed herein. The waveguide power dividers comprise an input port for receiving an input electromagnetic signal, a main output port for emitting a main output electromagnetic signal, and a subsidiary output port for emitting a subsidiary output electromagnetic signal. A main waveguide extends between the input port and the main output port and a subsidiary waveguide extends between the subsidiary output port and first and second connection points with the main waveguide. A horizontal polarizer regulates the distribution of horizontal polarized signal between the main output port and subsidiary output port and a vertical polarizer regulates the distribution of vertical polarized signal between the main output port and subsidiary output port. The waveguide power dividers disclosed herein may be used in array antennas.

Dependent claims

A waveguide power divider comprising:

(a) an input port for receiving an input electromagnetic (EM) signal comprising a horizontal polarization state and a vertical polarization state;
(b) a main output port for emitting a main output EM signal;
(c) a main waveguide extending between the input port and the main output port, the main waveguide for transmitting a first portion of the horizontal polarization state and a first portion of the vertical polarization state from the input port to the main output port, the main waveguide comprising a square cross-section;
(d) a subsidiary output port for emitting a subsidiary output EM signal;
(e) a subsidiary waveguide connected to the main waveguide at a first connection point and at a second connection point, the subsidiary waveguide extending between the first connection point, the second connection point, and the subsidiary output port;
(f) a first horizontal polarizer for permitting passage of a second portion of the horizontal polarization state from the first connection point to the subsidiary output port and for preventing passage of the vertical polarization state from the first connection point to the subsidiary output port;
and
(g) a first vertical polarizer for permitting passage of a second portion of the vertical polarization state from the second connection point to the subsidiary output port and for preventing passage of the horizontal polarization state from the second connection point to the subsidiary output port.
