Frequency adjustable antenna apparatus and a manufacturing method thereof

A frequency adjustable antenna apparatus, comprising:

• a body;
• a first path located on an upper surface of the body and extending to a lower surface;
• at least one second path located on the lower surface of the body;
• a third path located on the lower surface of the body;
• and
• a printed circuit board having at least one soldering pad;
• wherein, when the lower surface of the body is pasted on the printed circuit board, the first path provides a first frequency and the third path provides a second frequency, and the first path is connected with the second path and/or the third path is connected with the second path via the soldering pads of the printed circuit board;
• wherein the length of the first path and/or the third path of the antenna apparatus is changed to adjust the frequency of the antenna apparatus to provide a dual-frequency frequency adjustable antenna apparatus.

A frequency adjustable antenna apparatus, comprising:

• a body;
• a plurality of paths located on an upper surface and a lower surface of the body;
• a printed circuit board having at least one soldering pad;
• wherein, when the lower surface of the body is pasted on the printed circuit board, the plurality of paths are connected together via the soldering pads of the printed circuit board;
• wherein the length of the paths of the antenna apparatus are changed to adjust the frequency of the antenna apparatus.

A manufacturing method for a frequency adjustable antenna apparatus, the steps comprising;

• manufacturing a body;
• disposing a plurality of paths on the body;
• wherein the plurality of paths are disposed on an upper surface and a lower surface of the body;
• and
• manufacturing a printed circuit board;
• wherein there are a plurality of soldering pads on the printed circuit board and the plurality of soldering pads are located on the locations that correspond to the ends of the plurality of paths;
• wherein, when the lower surface of the body is pasted on the printed circuit board, some of the plurality of paths are connected together via the soldering pads of the printed circuit board
• wherein the length of the antenna path of the antenna apparatus is changed to adjust the frequency of the antenna apparatus.
