Problems solved by technology
But there are the following defects: the diversity unit and the WIFI unit both use independent antennas, which can lead to too many antennas in the same product, and there is a problem of interference coexistence; and the diversity unit and the GPS unit use one antenna, which requires a radio frequency switch to switch, and the two cannot be used at the same time

The invention provides a composite antenna for a mobile phone terminal, which includes a casing and an antenna part. The antenna part includes a radiator, a feeding part, a switch and an inductor. The radiator is in the shape of a cover with one end open, and the shell is a hollow polygon with two ends open. The open end of the radiator is connected to an open end of the shell through an insulating medium. connected. The feed part is connected to the feed source, the feed part and the switch part are located at the upper end of the connection between the radiator and the shell, the inductance is located at the lower end of the joint between the radiator and the shell, and the feed part, the switch, and the inductor are connected to the radiator and the shell are connected. When the switch is turned off, the present invention realizes the composite of the diversity antenna and the WIFI antenna, and realizes the composite of the diversity antenna, the GPS antenna and the WIFI antenna when the switch is closed. The present invention can simultaneously work in the three working frequency bands of diversity reception, GPS communication and WIFI communication, thereby simplifying the design of the antenna, reducing the use space, and adapting to the trend of reducing the space size of the antenna.
Description
technical field [0001] The invention relates to the technical field of antenna design, in particular to a composite antenna for a mobile phone terminal. Background technique [0002] With the rapid development of mobile communication, the functions of mobile terminals are becoming more and more abundant, and applications such as GPS, BT / WIFI (2.4GHz), and WIFI (5GHz) are gradually becoming popular, and more antennas are needed to cover new frequency bands. More and more The mobile terminal not only has one main antenna, but also combines many auxiliary antennas, such as GPS antenna, BT antenna and WIFI antenna. However, the space left for the antennas inside the mobile terminal is very limited, and these antennas will occupy a certain space inside the mobile terminal, so the space factor of the antenna restricts the development of the miniaturization of the mobile terminal. Therefore, in the current situation where the external size and internal space of the mobile terminal...
