Abstract

A new type circuit board antenna is proposed. There is a circuit board having a surface. A first strip conducting part locates at the surface of the circuit board. A first U-type conducting part locates at the surface of the circuit board and connects with the first strip conducting part. A second U-type conducting part locates at the surface of the circuit board and is complementary with the first U-type conducting part. A grounding part locates at the surface of the circuit board and connects with the first strip conducting part. A second strip conducting part connects with the second U-type conducting part and combines the ground part as a micro strip for conducting the antenna signal.

Claims

1. A new type circuit board antenna comprises:

a circuit board having a surface;

a first strip conducting part locating at said surface of said circuit board;

a first U-type conducting part locating at said surface of said circuit board and connecting with said first strip conducting part;
