Abstract
A dipole antenna includes a reflector, a radiating element, and a feed element. The radiating element includes first and second dipoles above a surface of the reflector. The first and second dipoles respectively include arm segments and are arranged in a crossed dipole arrangement. The feed element includes first and second conductive transmission lines that are electrically isolated from one another and are capacitively coupled to the arm segments of the first and second dipoles, respectively. The arm segments of the first and second dipoles are between the feed element and the surface of the reflector.

A dipole antenna, comprising:
- a reflector;
- and
- a radiating element comprising arm segments defining first and second dipoles that are arranged in a crossed dipole arrangement above a surface of the reflector, the arm segments comprising substantially planar top surfaces and side surfaces at edges of the substantially planar top surfaces,
- wherein the substantially planar top surfaces extend over a majority of an area between opposing sides of the arm segments,
- wherein the side surfaces of the arm segments extend toward the reflector,
- wherein each of the arm segments comprises at least two of the side surfaces,
- wherein the substantially planar top surfaces of the arm segments define respective closed rectangular shapes in plan view, and
- wherein one of the arm segments of the first dipole and one of the arm segments of the second dipole comprise respective openings therein through which first and second conductive transmission lines are coupled, respectively.
A method of fabricating a dipole antenna, the method comprising:
- providing a reflector;
- and
- providing a radiating element comprising arm segments defining first and second dipoles that are arranged in a crossed dipole arrangement above a surface of the reflector, the arm segments comprising substantially planar top surfaces and side surfaces at edges of the substantially planar top surfaces,
- wherein the substantially planar top surfaces extend over a majority of an area between opposing sides of the arm segments,
- wherein the side surfaces of the arm segments extend toward the reflector,
- wherein each of the arm segments comprises at least two of the side surfaces,
- wherein the substantially planar top surfaces of the arm segments define respective closed rectangular shapes in plan view, and
- wherein one of the arm segments of the first dipole and one of the arm segments of the second dipole comprise respective openings therein through which first and second conductive transmission lines are coupled, respectively.
