摘要： The present invention relates to a band rejection filter. The band rejection filter includes a first signal transmission channel called a direct channel and a second signal transmission channel called a secondary channel. The direct channel and the secondary channel being designed to introduce at a first rejection frequency a phase difference of 180° between the signal circulating via the direct channel and the signal circulating via the secondary channel. Additionally, the secondary channel includes a filtering element for which the cut-off frequency is different from the first rejection frequency in a way to create a second rejection frequency.

It applies more specifically in the scope of terminals operating according to the standard IEEE 802.11n and employing simultaneously several frequency channels in a predetermined band of frequencies, for example the 5 GHz WiFi band. The terminal comprises M antennas, a MIMO device able to generate MIMO signals in said predetermined frequency band from baseband signals or conversely, said MEMO device being able to process N MIMO signals simultaneously, and a switching device to connect the MIMO device to the M antennas. According to the invention, the NINO device comprises two MIMO circuits, one operating in a first sub-band of the predetermined band and the other in a second sub-band of the predetermined band, the two sub bands being non-overlapping and the switching device is adapted to connect said two MIMO circuits to the antennas so that each of said M antennas is able to receive or transmit one of the MIMO signals of the first MIMO circuit and to receive or transmit one of the MIMO signals of the second MIMO circuit simultaneously. The switching device also comprises a filtering device associated with each antenna in order to isolate, in reception, the MIMO signal of the first sub-band of the MIMO signal from the second sub-band received or transmitted by said antenna.
