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, and 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
a pole-mounting bracket comprising a base plate and a back plate, wherein the back plate includes at least one clamp slot, wherein the base plate is situated between the reflector and the rear housing, and wherein the base plate is operable to be coupled to the reflector 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.

2. The antenna assembly of claim 1 , further comprising:
a pole clamp for mounting the reflector to a pole, wherein a bolt of the pole clamp is inserted into the clamp slot.

3. The antenna assembly of claim 1 , wherein the clamp slot has an elongated shape with a curvature that allows the pole clamp to be rotated along the clamp slot within a predetermined range against a pivot point of the back plate.

4. The antenna assembly of claim 1 , further comprising:
a push latch that passes through a fastener opening of the reflector, and engages to the front side of the reflector.

5. The antenna assembly of claim 4 , wherein inserting the push latch into the fastener opening prevents the push latch from becoming disengaged from the reflector.

6. The antenna assembly of claim 1 , further comprising:
a locator-pin opening at an off-center position of the reflector; and
a locator pin on the rear housing at a position corresponding to the locator-pin opening of the reflector.

7. The antenna assembly of claim 6 , wherein inserting the locator pin into the locator-pin opening prevents the pole-mounting bracket from rotating.

8. The antenna assembly of claim 6 , wherein the reflector comprises two locator-pin openings at opposing sides of the center opening.

9. 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.

10. The antenna assembly of claim 1 , wherein the feed tube houses a transceiver circuit.

11. The antenna assembly of claim 1 , wherein the feed-antenna subassembly includes a data port at a proximal end of the feed-antenna subassembly, and wherein when the feed-antenna subassembly is mounted to the reflector, the data port is exposed at a convex side of the reflector.

12. The antenna assembly of claim 11 , wherein the data port includes an Ethernet port, and wherein the Ethernet port allows power over Ethernet.

13. The antenna assembly of claim 1 , 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.

14. The antenna assembly of claim 13 , wherein decoupling the feed-antenna subassembly and the rear housing requires a prior release of the push latch from the rear housing.
