Mobile communication base station based on metamaterial antenna

Abstract

A mobile communication base station based on a metamaterial antenna comprises a content access module, a radio remote module, a software radio configuration module and the metamaterial antenna. The content access module receives contents of communication signals of various systems provided by various information sources; the radio remote module is used for converting the communication signals of the various systems between analog radio-frequency signals and baseband signals and processing redundancy in the radio-frequency signals; the software radio configuration module carries out corresponding configuration on the communication signals of the various systems processed by the radio remote module for the metamaterial antenna; the metamaterial antenna converts electrical signals into electromagnetic waves or allows the electromagnetic wave to be converted into the electrical signals. Therefore, consistency of analog discrete components of the mobile communication base station is kept, and consistency of the amplitude and the phase of the signals is guaranteed; the size of a product becomes small, the weight of the product is reduced, and thus miniaturization, a light-weight trend and integration of the whole mobile communication base station are achieved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a mobile communication base station based on a metamaterial antenna. Background technique [0002] At present, in base stations, base station subsystems, repeaters and other systems of wireless mobile communication systems such as GSM, CDMA, TD-SCDMA, and WACDMA, analog technology is generally used to process out-of-band useless signals in order to realize mobile communication signal processing. frequency selection function. In the current analog communication system, a signal frequency selection processing technology is widely used, which is composed of a series of devices such as mixers, amplifiers and SAW filters. The input RF signal is processed by frequency mixing, and the analog intermediate frequency signal is output, and then through the amplification process to offset the difference caused by the frequency mixing process, and the out-of-band signal is fil...
