Single or dual polarized molded dipole antenna having integrated feed structure
First Claim
1. A polarized antenna comprising:
- at least one dipole having a base portion and a plurality of radiating arms extending therefrom, wherein said dipole is a unitary structure; and
a reflector plate to which the base portion is attached, said reflector plate being a ground plane and reflecting polarized radio frequency signals;
wherein said plurality of radiating arms are divided into two sets including a first set and a second set respectively having a first polarization and a second polarization corresponding to two polarizations of said dipole body;
wherein each of said first and second sets includes two pairs of arms arrange in a V-shape and having a vertex portion.

Abstract
A polarized antenna for sending and receiving polarized radio frequency signals is disclosed which includes a dipole and a reflector plate. The dipole is formed as a single part including the radiating arms and feeding structures, thereby requiring minimum assembly. This dipole can be formed by molding conventional materials, such as copper, aluminum, and plastic, which can then be plated. The feeding structure through which the cable passes features a slotted aperture. The impedance of the dipole is based on the width of these apertures and the size of the cable conductor. By having a single-body construction, the dipole of the present invention provides, good impedance, low intermodulation distortion, good port-to-port isolation, and good pattern purity.
