Abstract
In accordance with the teachings described herein, a multilevel ground-plane for a mobile device is provided. The multilevel ground-plane includes a first conductive surface, a second conductive surface, and a conducting strip that couples the first conducting surface to the second conducting surface. A mobile device having a multilevel ground-plane may include a printed circuit board, an antenna radiating element attached to a surface of the printed circuit board, and the multilevel ground plane integral with the printed circuit board and electromagnetically coupled to the antenna radiating element.
Claims35
A mobile device, comprising:
- a printed circuit board;
- an antenna radiating element attached to a surface of the printed circuit board;
- and
- a multilevel ground plane integral with the printed circuit board and electromagnetically coupled to the antenna radiating element;
- the multilevel ground plane comprising:
- a first conducting surface;
- a second conducting surface;
- and
- a conducting strip that couples the first conducting surface to the second conducting surface;
- wherein at least a portion of the multilevel ground plane defines a space-filling curve;
- and
- wherein at least one edge of the antenna radiating element is aligned with a slot defined between the first conducting surface and the second conducting surface.
An antenna system, comprising a radiating element placed over a ground plane, the radiating element having at least one edge and the ground plane having at least one slot, wherein at least a part of one edge of the radiating element is positioned over a part of one slot of the ground plane.
