Abstract

A dual-frequency antenna and its wireless communication terminal. The invention discloses a dual-frequency antenna, which comprises a bent dipole antenna and a sleeve dipole antenna, and the dipole antenna and the sleeve dipole antenna are located on the same plane. The dual-frequency antenna of the present invention is combined on the same plane through the dipole antenna and the sleeve dipole antenna, and the first and second radiation arms of the dipole antenna are respectively integrally formed with the radiation arms and the grounding part of the sleeve dipole antenna, The size of the antenna is effectively reduced, which conforms to the trend of miniaturization of the antenna, and the structure is simple and easy to produce, which indirectly improves the production efficiency of the factory and saves the manufacturing cost. In addition, the dual-frequency antenna of the present invention greatly increases the bandwidth of the antenna by exciting multiple resonance modes, and effectively improves the radiation frequency of the antenna.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a dual-frequency antenna applied to the field of wireless communication. Background technique [0002] Antennas are important components in wireless communication terminals. Examples of wireless communication terminals include mobile phones, computers, set-top boxes, personal digital assistants (PDAs), e-books, multimedia players, radios, and the like. An antenna in a wireless communication terminal acts as an air interface for transmitting and receiving radio frequency (RF) waves. [0003] As a kind of antenna, the dipole antenna is widely used because of its high gain, light weight, simple structure, stable and reliable performance, good sealing performance, and small space occupation. For example, in the prior art, the Chinese Invention Patent Publication No. CN1625821A, which was applied by Israel Geertronix Company, discloses a multi-band sleeve dipole antenna, which i...
