Abstract
The disclosure relates to a planar antenna comprising at least one radiator element separated from a ground plane by a dielectric. The antenna also comprises an assembly of conductive studs which is connected to and extends from at least one element of a group of elements comprising the ground plane and at least one radiator element in such a way that at least one physical dimension of said at least one radiator element for a determined resonance frequency is reduced.
Claims26
A planar antenna comprising:
- at least one radiating element separated from a ground plane by at least a dielectric and wherein the at least one radiating element is not in direct electrical contact with the ground plane;
- and
- a plurality of conductive studs, wherein the plurality of conductive studs i) are electrically connected to only the at least one radiating element and extend toward the ground plane without contacting the ground plane and without extending beyond a planar surface of the ground plane nearest the at least one radiating element, or ii) are electrically connected to only the ground plane and extend toward the at least one radiating element without contacting the at least one radiating element.
A planar antenna comprising:
- a first radiating element separated from a ground plane by at least a dielectric;
- and
- a first plurality of conductive studs, wherein the first plurality of conductive studs are electrically connected only to the first radiating element and extend from a surface of the first radiating element toward a second radiating element without contacting the second radiating element.
A method for manufacturing a planar antenna, the method comprising:
- separating a first radiating element from a ground plane by a dielectric, wherein a first dielectric surface of the dielectric is adjacent to a first radiating surface of the first radiating element, and further wherein a second dielectric surface of the dielectric is adjacent to a first ground surface of the ground plane;
- and
- mounting a first plurality of conductive studs to the planar antenna, wherein the first plurality of conductive studs are i) mounted to the first radiating element such that the first plurality of conductive studs extend toward the ground plane without contacting the ground plane and without extending beyond a planar surface of the ground plane nearest the first radiating element, and electrically connected only to the first radiating element, ii) mounted to the ground plane such that the first plurality of conductive studs extend toward the first radiating element without contacting the first radiating element, and electrically connected only to the ground plane, or iii) mounted to the first radiating element such that the first plurality of conductive studs extend from a surface of the first radiating element toward a second radiating element without contacting the second radiating element, and electrically connected only to the first radiating element.
