Abstract
A waveguide rotary joint includes a first waveguide member comprising a first waveguide portion, and a second waveguide member comprising a second waveguide portion, the second waveguide member rotatably connected via a curved circumferential path to the first waveguide member, wherein the second waveguide portion is adjacent to the first waveguide portion to define a first split rectangular waveguide. A first waveguide input/output port is communicatively coupled to the first waveguide portion, and a second waveguide input/output port is communicatively coupled to the second waveguide portion. Relative rotation between the first waveguide member and the second waveguide member changes an angular length of the first waveguide connecting the first waveguide input/output port to the second waveguide input/output port.
