Abstract

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.

First claim

What is claimed is:

1. An antenna assembly, comprising:
a reflector comprising a center opening;
a rear housing situated on a convex side of the reflector, wherein the rear housing comprises a center cavity;
a feed-antenna subassembly situated on a concave side of the reflector, wherein the feed-antenna subassembly comprises a feed tube, wherein a proximal end of the feed tube is operable to be inserted in and coupled to the center cavity of the rear housing, with the reflector situated between the feed-antenna subassembly and the rear housing, and wherein the feed-antenna subassembly further comprises a push latch that passes through the center cavity of the rear housing and engages to a latch opening of the rear housing; and
a transceiver circuit situated inside the feed tube, wherein the transceiver circuit is coupled to a data port accessible from a proximal side of the feed-antenna subassembly, such that when the feed-antenna subassembly is mounted to the concave side of the reflector, the data port becomes exposed at a convex side of the reflector.

2. The antenna assembly of claim 1 , wherein the transceiver circuit comprises printed circuit board (PCB) for a transmitter and receiver circuit, and wherein the data port is mounted on the PCB.

3. The antenna assembly of claim 1 , wherein the transceiver circuit receives power over the data port.

4. The antenna assembly of claim 1 , wherein the data port includes an Ethernet port, and wherein the Ethernet port allows power over Ethernet.

5. The antenna assembly of claim 1 , further comprising a sub-reflector inside the feed tube, near a distal end of the feed-antenna subassembly.

6. The antenna assembly of claim 1 , further comprising a feed cap at a distal end of the feed-antenna subassembly.

7. The antenna assembly of claim 1 , wherein the push latch is configured in such a way that decoupling the feed-antenna subassembly and the rear housing requires a prior release of the push latch from the rear housing.

8. The antenna assembly of claim 1 , wherein the center opening of the reflector has a shape matching a profile of the proximal end of the rear housing.

9. The antenna assembly of claim 1 ,
wherein the rear housing further comprises a push latch operable to pass through a fastener opening of the reflector, and engage to the front side of the reflector.

10. The antenna assembly of claim 9 , wherein the push latch of the rear housing is configured in such a way that inserting the push latch of the rear housing into the fastener opening prevents the rear housing from becoming disengaged from the reflector.
