Abstract
In one example, a dual-band wireless LAN antenna. The antenna includes plural antenna traces disposed in a first plane that is substantially parallel to, and spaced apart from, a plane of electrically conductive material. At least two of the traces are dimensioned to resonate at different frequencies. The antenna also includes a decoupling element disposed in a second plane between the first plane and the conductive plane. The decoupling element is electrically connected to a selected one of the antenna traces. The antenna further includes a conductor which is electrically connected to the decoupling element and to the conductive plane.
Claims15
An electronic device, comprising:
- an enclosure having a windowless metal cover;
- and
- a dual-band wireless LAN antenna, disposed adjacent the windowless metal cover, having
- plural antenna traces disposed in a first layer substantially parallel to the windowless metal cover,
- a decoupling element disposed in a second layer disposed between the first layer and the windowless metal cover and electrically connected to one of the antenna traces, and
- a conductor electrically connecting the decoupling element to the windowless metal cover.
A dual-band omnidirectional wireless LAN antenna, comprising:
- plural antenna traces disposed in a first plane substantially parallel to, and spaced apart from, a plane of electrically conductive material, at least two of the traces dimensioned to resonate at different frequencies;
- a decoupling element disposed in a second plane between the first plane and the conductive plane and electrically connected to a selected one of the antenna traces;
- and
- a conductor electrically connected to the decoupling element and the conductive plane.
A method of fabricating a dual-band omnidirectional wireless LAN antenna, comprising:
- disposing, in a first plane, conductive traces for first and second antennas each having a different resonant frequency, the first plane adjacent a windowless conductive sheet;
- disposing, in a second plane between the first plane and the conductive sheet, a conductive trace for a decoupling element to decouple the first antenna from the conductive sheet;
- and
- electrically connecting the decoupling element to the first antenna and to the conductive sheet.
