Configurable horn antenna

摘要

A configurable antenna may include a circular horn array comprising a plurality of horn antennas, a configurable waveguide in a center of the circular horn array, and a plurality of actuators. The configurable waveguide includes a plurality of retractable triangular wedges, with one side of each wedge oriented to one of the plurality of horn antenna and a corner oriented toward a center of the waveguide, wherein a circle defined by each of the corners oriented toward the center of the waveguide defines a first circumference. The configurable waveguide further includes a plurality of movable tuning rods arranged in a circle defining a second circumference, the second circumference being smaller than the first circumference, said movable tuning rods further arranged such that the movable tuning rods are between the corners the corners oriented toward the center of the waveguide.

1. A configurable antenna, comprising:
a. a circular horn array comprising a plurality of horn antennas; b. a configurable waveguide in a center of the circular horn array, the configurable waveguide including a plurality of movable elements to configure a shape of the configurable waveguide and to selectively couple the configurable waveguide to selected horn antennas of the circular horn array; c. a plurality of actuators linked to the movable elements, wherein each of the plurality of movable elements comprises a wedge, wherein each wedge is associated with one of the plurality of horn antennas, and wherein the configurable wave guide further comprises a plurality of movable tuning rods arranged in a circle and offset from the wedges, and wherein a given horn antenna is coupled to the configurable wave guide when the corresponding wedge and adjacent tuning rods are retracted.
