US 2006/0152428 A1 · Dipole antenna

Abstract

A dipole antenna is provided. A radiation portion receives radio signals. A first matching portion includes a body section with one terminal connecting to the radiation portion, and a feed section connecting to another terminal of the body section. A second matching portion has one terminal connecting to the radiation portion to brace the radiation portion with the first matching portion in a cooperative manner. A ground portion connects to another terminal of the second matching portion. The radiation portion has an electric length of a half of a wavelength. The two matching portions have an electric length of a quarter of a wavelength. The radiation portion and the matching portions may be formed in an integrated manner.
