Abstract
An antenna assembly and a method of configuring the antenna assembly can include a ground plane on a printed circuit board, a plastic substrate that supports an antenna, a metal radiating element mounted to the plastic substrate, and a radiating element mounted above the ground plane and including multiple branches above the ground plane to achieve wideband frequencies. A feeding leg can support a first branch of the radiating element above the ground plane and can electrically couple the first branch to an RF feeding port and impedance matching network. A ground leg can support a second branch of the radiating element above the ground plane and can electrically couple the second branch to the ground plane.
Claims6
An antenna assembly, comprising:
- a ground plane formed on a printed circuit board;
- a plastic substrate mounted on, and disposed perpendicular to, the printed circuit board;
- a metal radiating element mounted to the plastic substrate above the ground plane and including multiple branches above the ground plane to achieve wideband frequencies;
- a gasket located above the printed circuit board with respect to the ground plane and surrounding a portion of the metal radiating element;
- a feeding leg extending through the printed circuit board, the feeding leg electrically coupled to a first branch of the radiating element and adapted to couple the first branch to an RF feeding port;
- and
- a ground leg extending through the printed circuit board, the ground leg electrically coupling a second branch of the radiating element to the ground plane.
