Eight-frequency band reconfigurable intelligent mobile phone antenna

Abstract

The invention discloses an eight-frequency band reconfigurable intelligent mobile phone antenna, and mainly solves the problems of failure in designing a small-size, low-section and multiple-frequency wideband intelligent mobile phone antenna in a given environment in the prior art, and failure in meeting the technical development requirement. The eight-frequency band reconfigurable intelligent mobile phone antenna comprises a housing, a dielectric plate in the housing, a metal plate on one surface of the dielectric plate, and further comprises a second bent metal strip group and a first bent metal strip group, wherein both the second bent metal strip group and the first bent metal strip group are arranged on the other surface of the dielectric plate; a feeding point (1) is connected to the first bent metal strip group; the first bent metal strip group as well as the second bent metal strip group comprises at least two metal strips, a diode, a patch inductor and a patch capacitor; the diode, the patch inductor and the patch capacitor are connected between the metal strips. According to the scheme, the purposes of miniaturization, eight working frequency covering capability and higher performance-price ratio are realized; the utility value and the popularization value are higher.

Description

technical field [0001] The invention relates to a mobile phone antenna, in particular to an eight-band reconfigurable smart phone antenna. Background technique [0002] With the rapid development of communication systems, mobile phones have expanded from only providing a single voice call service to multimedia services such as Internet access. At present, since the network standards and frequency bands adopted by network operators in various countries are different, designing an antenna that can work in multiple frequency bands has become the main goal of antenna design. [0003] As the access control for transmitting and receiving electromagnetic wave signals, the mobile phone antenna plays a vital role in the working performance of the whole mobile phone system. In the prior art, multiple antenna branches are usually designed to enable the designed antenna to work in multiple frequency bands, but This method will inevitably take up more area, so the size of the mobile ph...
