Abstract

A miniature wire antenna includes N rectangular metal plates located at a first layer of a PCB, a tunable metal plate located at the first layer of the PCB and N serpent lines located at a second layer of the PCB. The positions of the N serpent lines correspond to the positions of the rectangular metal plates. A first end of each of the serpent lines is connected to the corresponding rectangular metal plate, and a second end of each of the serpent lines is connected to the next rectangular metal plate. A first end of the last serpent line is connected to the corresponding rectangular metal plate, and a second end of the last serpent line is connected to the tunable metal plate.

Claims

1. A miniature wire antenna comprising:

N rectangular metal plates located at a first layer of a PCB;

a tunable metal plate located at the first layer of the PCB; and

N serpent lines located at a second layer of the PCB;

wherein the positions of the N serpent lines correspond to the positions of the N rectangular metal plates;

a first end of each of the serpent lines is connected to the corresponding rectangular metal plate, and a second end of each of the serpent lines is connected to the next rectangular metal plate;

a first end of the last serpent line is connected to the corresponding rectangular metal plate, and a second end of the last serpent line is connected to the tunable metal plate.

2. The miniature wire antenna according to claim 1, wherein the tunable metal plate is a rectangular metal plate.

3. The miniature wire antenna according to claim 1, wherein part of the tunable metal plate is a miniature wire antenna.

4. The miniature wire antenna according to claim 1, wherein the miniature wire antenna is a single band wireless local area network (WLAN) antenna or a global positioning system (GPS) antenna.

5. The miniature wire antenna according to claim 4, wherein the miniature wire antenna is a dual band WLAN antenna or an ultra wide band antenna.

6. The miniature wire antenna according to claim 1, wherein the PCB further comprises multiple vias for connecting the rectangular metal plates and the serpent lines.
