Claim Text:
1. A method for filtering out adjacent frequency band interference, comprising: receiving, by a Radio Frequency Micro Electro Mechanical System (RF MEMS) switch control module, a first transmitted coupling signal from a first frequency band RF module and a second received coupling signal from a second frequency band RF module, wherein the first frequency band RF module works in a first frequency band and the second frequency band RF module works in a second frequency band; and determining, by the RF MEMS switch control module, whether interference exists between the first frequency band and the second frequency band according to the first transmitted coupling signal and the second received coupling signal; if interference exists, filtering out, by the RF MEMS switch control module, the interference by instructing a first frequency band RF MEMS antenna working in the first frequency band to change a first antenna structure and/or by instructing a second frequency band RF MEMS antenna working in the second frequency band to change a second antenna structure; wherein the first transmitted coupling signal is formed by coupling, through the first frequency band RF module, a predetermined proportion of enemy of a digital baseband signal which needs to be sent, to the RF MEMS switch control module; and the second received coupling signal is formed by coupling, through the second frequency band RF module, a predetermined proportion of enemy of a demodulated received digital baseband signal, to the RF MEMS switch control module; wherein a first working frequency band group of the first frequency band RF MEMS antenna is reconfigurable and comprises at least two different working frequency bands; and a second working frequency band group of the second frequency band RF MEMS antenna is reconfigurable and comprises at least two different working frequency bands; wherein a frequency band section of the second working frequency band group is adjacent to a frequency band section of the first working frequency band group.
