Abstract

The Figures illustrate an apparatus 2 comprising: a conductive element 4 comprising an area of conductive material 5 defined by a plurality of edges 6, 7 including a first edge 7 wherein the conductive element 4 comprises an interior aperture 12 in the area of conductive material 5 and an elongate portion 20 defined by a gap 14 at the first edge 7 of the conductive element 4 and by at least a portion of the interior aperture 12 . The apparatus 2 may comprise a further interior aperture in the area of conductive material and a second elongate portion defined by a second gap, by at least a portion of the interior aperture and by at least a portion of the further interior aperture.

Claims (29)

1. An apparatus comprising:

a conductive element comprising an area of conductive material defined by a plurality of edges including at least a first edge wherein the conductive element comprises:

a first interior aperture in the area of conductive material and a first elongate portion defined by a first gap at the first edge of the conductive element and by at least a portion of the interior aperture; and

a second interior aperture in the area of conductive material and a second elongate portion defined by a second gap, by at least a portion of the first interior aperture and by at least a portion of the second interior aperture, and

further comprising at least one of a lumped reactive element and a distributed reactive element bridging the first gap; and

a feed element associated with the second elongate portion,

wherein the first interior aperture is positioned adjacent to the first edge and is an aperture that is wholly within a boundary of the conductive element and the second interior aperture is positioned adjacent to the first interior aperture and is wholly within the boundary of the conductive element, and wherein the first interior aperture is parasitically fed by the second interior aperture.

2. The apparatus according to claim 1 , wherein the feed element is an indirect feed element adjacent to but separated from the second elongate portion and separated from the conductive element.

3. The apparatus according to claim 1 , further comprising at least one of a lumped reactive element and a distributed reactive element bridging the second gap.

4. The apparatus according to claim 1 , wherein the first interior aperture and the second interior aperture are both elongate and substantially parallel.

5. The apparatus according to claim 1 , wherein the first interior aperture and the second interior aperture are both elongate and have substantially the same length.

6. The apparatus according to claim 1 , wherein the first interior aperture and the second interior aperture are both elongate and have substantially the same width.

7. The apparatus according to claim 1 , wherein the second interior aperture has a substantially rectangular perimeter that has an outwardly extending notch through to the first interior aperture that forms the second gap.

8. The apparatus according to claim 1 , wherein one or more of the first gap and the second gap are positioned to maximize a length of one or more of the first elongate portion and the second elongate portion.

9. The apparatus according to claim 1 , wherein the conductive element is configured as a ground plane for a communications device.

10. The apparatus according to claim 1 , wherein the conductive material is supported by a substantially planar dielectric support having opposing first and second faces and wherein the first face supports the conductive material having the first interior aperture, the first elongate portion, the second interior aperture, and the second elongate portion, and wherein the second face provides the feed element.

11. The apparatus according to claim 10 , wherein the second face supports conductive material that is substantially absent in an area corresponding to the second interior aperture except for the feed element and a conductive tab, wherein at least a portion of the feed element and the conductive tab are positioned to correspond with the second elongate portion.

12. The apparatus according to claim 11 , wherein the length of the conductive tab is controlled to enable the apparatus to operate as an antenna at least at a desired resonant frequency.

13. The apparatus according to claim 10 , wherein the length of the portion of the feed element that corresponds with the elongate portion is controlled to enable the apparatus to operate as an antenna at least at a desired resonant frequency.

14. The apparatus according to claim 1 , wherein the conductive element is a printed wiring board.

15. The apparatus according to claim 1 , wherein the conductive element is configured as a radiator that enables the apparatus to operate as a dual-band antenna.

16. The apparatus according to claim 1 , wherein the feed element is a direct feed element configured to couple to the second elongate portion.

17. An electronic device comprising:

a conductive element comprising an area of conductive material defined by a plurality of edges including at least a first edge wherein the conductive element comprises:

a first interior aperture in the area of conductive material and a first elongate portion defined by a first gap at the first edge of the conductive element and by at least a portion of the interior aperture; and

a second interior aperture in the area of conductive material and a second elongate portion defined by a second gap, by at least a portion of the first interior aperture and by at least a portion of the second interior aperture, and

further comprising at least one of a lumped reactive element and a distributed reactive element bridging the first gap; and

a feed element associated with the second elongate portion,

wherein the first interior aperture is positioned adjacent to the first edge and is an aperture that is wholly within a boundary of the conductive element and the second interior aperture is positioned adjacent to the first interior aperture and is wholly within the boundary of the conductive element, and wherein the first interior aperture is parasitically fed by the second interior aperture.
