DEVICES AND METHODS FOR REDUCING INTERFERENCE BETWEEN CLOSELY COLLOCATED ANTENNAS |
摘要 |
Devices and methods for reducing interference between closely collocated antennas working at the same or adjacent frequencies are disclosed. According to one embodiment, the antenna array comprises a plurality of antennas for transmitting signals from and receiving signals to a plurality of transceivers respectively, and the device comprises a plurality of resonators; a first set of ports, each of which is connected to a respective one of the plurality of transceivers; and a second set of ports, each of which is connected to a respective one of the plurality of antennas; wherein each of the transceivers and the antennas is connected to a respective one of the resonators, and coupling coefficients among the resonators as well as a resonance frequency of each of the resonators are configured so that a desired isolation among the first set of ports and a desired matching at each of the first set of ports are obtained. |
