Antenna Apparatus and Device

An antenna apparatus comprising

• an antenna radiator comprising a top edge, a bottom edge, and a first side edge, wherein the bottom edge comprises an end;
• an antenna cable trough disposed on the antenna radiator and extending from the top edge to the bottom edge;
• a feedpoint disposed on the antenna radiator at the end and near the first side edge;
• and
• a first protruding metal strip inserted in the antenna cable trough and separated from the antenna radiator,
• wherein the antenna apparatus is configured to be disposed within a printed circuit board (PCB) metal layer.

A device comprising:

• a printed circuit board (PCB) comprising an edge;
• an antenna apparatus disposed near the edge;
• a PCB metal layer disposed on the PCB;
• and
• an antenna apparatus disposed within the PCB metal layer and comprising:
• an antenna radiator comprising a top edge, a bottom edge, and a first side edge near the edge, wherein the bottom edge comprises a first end;
• an antenna cable trough disposed on the antenna radiator and extending from the top edge to the bottom edge;
• a feedpoint disposed on the antenna radiator at the first end and near the first side edge;
• a feedpoint connecting the antenna radiator to the PCB metal layer;
• and
• a first protruding metal strip inserted in the antenna cable trough, separated from the antenna radiator, and comprising a second end connected to the PCB metal layer.
