Abstract

The invention discloses a multiband wireless terminal antenna, mainly solving the problems that the antenna in the prior art can not meet the requirements of people for miniaturization, high accuracy and convenience in use. The multiband wireless terminal antenna comprises a shell, a printed board and a printed board metal floor and also comprises a high-frequency resonance metal strip group, a low-frequency resonance metal strip group, a microstrip feeder and a stop band, wherein the printed board is arranged in the shell; the printed board metal floor is arranged on one surface of the printed board; the high-frequency resonance metal strip group is arranged on the other surface of the printed board; the low-frequency resonance metal strip group corresponds to the high-frequency resonance metal strip group; the microstrip feeder is connected with the end part of the high-frequency resonance metal strip group; the stop band is connected between the high-frequency resonance metal strip group and the microstrip feeder; and a coupling gap is arranged between the high-frequency resonance metal strip group and the low-frequency resonance metal strip group. By the scheme, the multiband wireless terminal antenna has the advantages that the purposes of small volume, high accuracy and convenience in use are achieved and the practical and promotional values are high.

Description

technical field [0001] The invention relates to a terminal antenna, in particular to a multi-band wireless terminal antenna. Background technique [0002] With the rapid development of the economy and the continuous updating of technology, the application of various wireless terminal equipment has become increasingly popular in people's life, entertainment, and office. Among them, the antenna for receiving radio is an indispensable less part. [0003] At present, people mainly use external antennas or patch antennas for signal reception. However, such antennas are large in size, poor in strength, and not beautiful enough to meet people's requirements for miniaturization of wireless terminal antennas and multi-band work. Although the existing printed board antenna has the advantages of small size, light weight and high strength, this kind of antenna still occupies a large area in actual use, and the design that occupies the edge of the circuit board is more, which is not con...
