Various embodiments of antenna assemblies are disclosed herein. In one embodiment, the antenna assembly includes a reflector comprising a center opening, a feed-antenna subassembly situated in front of the reflector, a rear housing situated behind the reflector, and a pole-mounting bracket comprising a base plate situated between the reflector and the rear housing. The feed-antenna subassembly comprises a feed tube that houses at least one of: a transmitter circuit and a receiver circuit. The rear housing is coupled to a front side of the reflector via the center opening. The rear housing comprises a center cavity, and a back end of the feed tube is inserted in and coupled to the center cavity. The base plate is coupled to the reflector and the rear housing in such a way that decoupling between the base plate and the reflector requires a prior decoupling between the feed-antenna subassembly and the rear housing and a prior decoupling between the rear housing and the reflector.

A symmetrical two-piece waveguide is described herein. The waveguide comprises an upper structure that forms a first symmetrical portion of at least one channel that defines an energy path between an input portion and a radiator portion of the channel. The waveguide further comprises a lower structure that forms a second symmetrical portion of the channel that is symmetrical to the first symmetrical portion about a separation plane when the upper and lower structures are mated. The upper structure further forms the radiator portion that extends orthogonally from an upper surface of the first symmetrical portion opposite the separation plane. The lower structure further forms the input portion that extends orthogonally from a lower surface of the second symmetrical portion opposite the separation plane. By using symmetry, the disclosed waveguide leverages the benefits of a two-piece design while enabling near-lossless channeling of energy without conductive bonding.
