Abstract
A small antenna comprising an unequal current density center-fed dipole employing a conductive trace and a ground plane counterpoise positioned substantially perpendicular to each other. According to one embodiment, a conductive trace is etched onto a dielectric substrate to form a printed circuit. According to a further embodiment, the conductive trace has two sets of orthogonal components; one set of components captures the desired electric field polarization and the second set of components cancels out the undesired cross polarization. A portion of a signal received on the first set of components adds together to produce a desired resultant vector and a portion of the signal received on the second set of components adds together to cancel out the undesired vector.

An antenna comprising an unequal current density center-fed dipole comprising a conducting trace and a ground plane counterpoise, wherein the conductive trace has first and second sets of components, and wherein a portion of a signal received on the first set of components does not produces a resultant vector and a portion of the signal received on the second set of components produce a resultant vector.
An antenna comprising:
- a ground plane counterpoise comprising a conductive material;
- a substrate coupled to and positioned with respect to the ground plane;
- and
- a conductive trace disposed on the substrate, wherein the substrate is coupled perpendicularly to the ground plane.
An antenna comprising:
- a first board;
- a second board positioned perpendicularly on the first board;
- a conductive trace coupled to the second board, wherein the conductive trace has a first and second set of components, and wherein a portion of a signal received on the first set of components does not produce a resultant vector and a portion of the signal received on the second set produces a resultant vector.
