Problems solved by technology

One is to use a planar inverted-F antenna (PIFA, planar inverted-F antenna) to transmit and receive multi-band antenna signals, but the PIFA antenna occupies a relatively large height and correspondingly occupies a large headroom, making it difficult to increase the frequency bands in different frequency bands. Antenna bandwidth of
The other is to set up multiple antennas and use each antenna to achieve different communication frequency bands, which also increases the space occupied by the antenna, and the design of multiple antenna units increases the cost of the antenna

Abstract

The invention provides an antenna device, a piece of electronic equipment and an antenna device setting method. The antenna device comprises a radiation part which is used for radiating and receiving antenna signals including a first antenna signal in a first frequency band and a second antenna signal in a second frequency band, a first feed end which is disposed in a first position of the radiation part and used for feeding the antenna signals between the radiation part and a first signal transceiver, a first matching unit which is used for matching the radiation part and the first signal transceiver to transmit the first antenna signal, a second feed end which is disposed in a second position of the radiation part and used for feeding the antenna signals between the radiation part and a second signal transceiver, and a second matching unit which is used for matching the radiation part and the second signal transceiver to transmit the second antenna signal. According to the technical scheme of the embodiment of the invention, multiband communication is realized under the condition of increasing a few additional devices and the design space.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to an antenna device, electronic equipment and a method for setting the antenna device. Background technique [0002] With the development of communication technology, the operating frequency band of electronic equipment is gradually increasing. Taking mobile communication terminals as an example, currently used 2G and 3G dual-mode mobile communication terminals require the working bandwidth of the antenna to be at low frequency 824-960MHz and high frequency 1710-2170MHz or 1710-2025MHz. In addition, the working frequency band of mobile communication terminals of TD-SCDMA and TD-LTE (4G) technology will also involve the frequency band in 2300MHz-2700MHz. Therefore, the development of communication technology needs to increase the operating frequency band of the antenna. [0003] In order to realize multi-band communication, the following antenna technology i...
