Terminal antenna

Abstract

A terminal antenna, which includes a flexural metal strip, a flexural metal plate, a ground line, a feed point line, an antenna feed point on one side of a printed board and a metal GND on the other side of the printed board. One end of the ground line is connected to the flexural metal plate and the other end is connected to the metal GND. One end of the feed point line is connected to the flexural metal strip and the other end is connected to the antenna feed point. There is a gap between the flexural metal strip and the flexural metal plate. In the invention, the terminal antenna with broad working bandwidth and high antenna efficiency can be achieved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to a terminal antenna. Background technique [0002] At present, the development of the communication system not only innovates the communication algorithm, but also puts forward higher and higher requirements for the design of the antenna, especially the antenna of the mobile phone. [0003] As an electrically small antenna, the mobile phone antenna's working bandwidth mainly depends on the space occupied by the mobile phone antenna. The larger the space, the wider the working bandwidth of the mobile phone antenna. However, in order to meet the sensory needs of the public, the current mobile phones are designed to be thinner and smaller in appearance and size, leaving insufficient space for mobile phone antennas. In addition, mobile phones generally integrate many communication systems, such as Bluetooth (Bluetooth, BT), Global Positioning System (Global Positioning Syste...

Problems solved by technology

However, in order to meet the sensory needs of the public, the current mobile phones are designed to be thinner and smaller in appearance and size, leaving insufficient space for mobile phone antennas.

In addition, mobile phones generally integrate many communication systems, such as Bluetooth (Bluetooth, BT), Global Positioning System (Global Positioning System, GPS), wireless Internet access (Wireless Fidelity, WIFI), etc., and the antennas of the corresponding communication systems also need take up some space

[0004] At present, the dilemma faced by mobile phone antennas is to design a wide enough working bandwidth as much as possible under the condition of limited space to meet the antenna efficiency requirements of the new generation of mobile communication networks. This is a technical problem.
