Abstract

An antenna structure formed on a circuit board includes a first main body formed on the lateral side of the circuit board and a feed line connecting the circuit board and the first main body. The first main body is formed on the lateral side of the circuit board by edge-plating.

Claims

1. An antenna structure formed on a circuit board, comprising:

a first main body formed on a lateral side of the circuit board; and

a feed line connected to the circuit board and the first main body.

2. The antenna structure as claimed in claim 1 further comprising a second main body adjacent to the first main body and formed on a front of the circuit board.

3. The antenna structure as claimed in claim 1, wherein the first main body is formed on the lateral side of the circuit board by edge-plating.

4. The antenna structure as claimed in claim 1, wherein the length of the first main body is longer than 14 mm and smaller than 40 mm when the material of the circuit board is glass fiber.

5. The antenna structure as claimed in claim 1, wherein the length of the first main body is longer than 18 mm and smaller than 50 mm when the material of the circuit board is polycarbonate.

6. The antenna structure as claimed in claim 1, wherein the length of the first main body is larger than 20 mm and smaller than 59 mm when the material of the circuit board is Teflon.

7. The antenna structure as claimed in claim 1, wherein the length of the first main body is longer than 8 mm and smaller than 25 mm when the material of the circuit board is silicon.

8. A method of forming an antenna structure, comprising the following steps:

providing a circuit board having a lateral side and a front;

plating the front and the lateral side; and

etching the circuit board to form a first main body on the lateral side and a second main body on the front, wherein the second main body is adjacent to the first main body.
