Claim Text:
1. A device for reducing interference between antennas in a compact antenna array, the antenna array comprising a plurality of antennas for transmitting signals from and receiving signals to a plurality of transceivers respectively, the device comprising: 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 at least two of the plurality resonators are cascade connected between each of the first set of ports and a corresponding one of the second set of ports; 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 performance at each of the first set of ports are obtained.
