Abstract
Antenna systems for access points and other wireless radio units include an RF ground plane, a radiating element mounted in front of the RF ground plane, and a coaxial feed cable coupled to the radiating element. The cable jacket includes a first opening that exposes a first portion of an outer conductor of the coaxial feed cable so that the cable jacket is on either side of the first opening along a longitudinal direction of the coaxial feed cable. The first portion of the outer conductor is galvanically connected to the RF ground plane via a first direct galvanic connection.
Claims20
An electronic device, comprising:
- a printed circuit board that comprises a radio frequency (“RF”) ground plane layer;
- a cable that on the printed circuit board, the cable comprising a conductor and a cable jacket that surrounds the conductor,
- wherein a first central portion of the conductor is connected to the RF ground plane layer via a first direct galvanic connection and a second central portion of the conductor is connected to the RF ground plane layer via a second direct galvanic connection.
A method of suppressing generation of intermodulation products, the method comprising:
- forming a first opening in a cable jacket of a coaxial feed cable for a radiating element of an antenna system to expose a first central portion of an outer conductor of the coaxial feed cable;
- and
- galvanically connecting the first central portion of the outer conductor to a radio frequency (“RF”) ground plane of the antenna system.
