Multi-sector antennas
First Claim
1. An antenna assembly having a first axis, the antenna assembly comprising:
- a first antenna section that is linearly between a second antenna section and a third antenna section, wherein the first, second and third antenna sections are in the first axis, further wherein each of the first, second and third antenna sections include;
an elongate trough extending in the first axis, wherein the elongate trough comprises a first wall, a second wall, and a base extending between the first wall and the second wall,an opening into the trough between the first wall and the second wall, wherein the opening has a width that is larger than a width at the base,a radiator array comprises an array of radiator elements arranged in a line at the base along in the first axis,a corrugation on the first wall along an edge of the first wall opposite the base comprising a plurality of ridges extending in the first axis, anda corrugation on the second wall along an edge of the second wall opposite the base comprising a plurality of ridges extending in the first axis; and
a first isolation plate between the first and second antenna section, and a second isolation plate between the second and third antenna sections, wherein the first and second isolation plates each comprise a plurality of ridges extending parallel to an outer edge and forming a corrugation along the outer edge.

Abstract
Multi-directional antenna assemblies including a plurality of individual antenna sections arranged in-line with a long axis, forming a linear assembly. An antenna assembly may include a radome over the linear assembly. A linear assembly may include three or more antenna sections, each with a trough-like reflector formed by two parallel walls, and may have corrugations at the outer edges to reduce noise. An array of radiators may be positioned at the base of each antenna section. The antenna sections may share a common vertical axis and each may have a beam axes that is offset by an angle. Adjacent antenna sections may be separated by an isolation plate with a corrugated outer edge. Each antenna section may radiate greater power in a specific direction as compared to the other antenna sections.
