Problems solved by technology

Please refer to figure 1 , the current practice is to debug these three frequency bands on one antenna. This antenna requires an effective area of ​​800 square millimeters and a few millimeters of headroom, which takes up a lot of space. If 5G that will be launched soon is added, The space required will be larger

Abstract

The invention discloses an RF communication device, which is characterized by comprising an RF communication module, an antenna switching switch, a first RF antenna, a second RF antenna and an antennamatching circuit, wherein the RF communication module, the first RF antenna and the second RF antenna are connected with the antenna switching switch respectively through the antenna matching circuit; and the antenna switching switch is used for connecting the RF communication module to the first RF antenna or the second RF antenna. As the RF antenna is divided to a low and medium-frequency antenna and a high-frequency antenna, the antenna switching switch is additionally arranged to control switching of the two RF antennas, and in general, space of more than 300 square millimeters can be reduced.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to an RF communication device. Background technique [0002] Existing mobile terminals are increasingly moving towards the integration of things, with more and more integrated functional modules, including 2G, 3G, 4G networks, WIFI communication, Bluetooth communication, fingerprint recognition, GPS positioning, RFID, and NFC communication etc. With so many functional modules installed in the mobile terminal, the space of the mobile terminal will obviously be insufficient under the current requirements for light, thin and small mobile terminals. [0003] The RF communication device in the mobile terminal mainly includes three frequency bands of 2G, 3G and 4G, and these three frequency bands cover 700MHz-2600MHz. Please refer to figure 1 , the current practice is to debug these three frequency bands on one antenna. This antenna requires an effective area of ​​8...
