Abstract
Devices and methods for decoupling two antennas in a compact antenna array and antenna arrays comprising the devices are disclosed. According to an embodiment, the device comprises a first resonator coupled with a source, the source being connected with a first antenna of the two antennas; and a second resonator coupled with the first resonator and a load, the load being connected with a second antenna of the two antennas, wherein the first and second resonators are configured so that a first coupling between the source and the first resonator, a second coupling between the first and second resonators, and a third coupling between the second resonator and the load are satisfied with a constraint that an isolation coefficient in a whole network composed of a first two-port network consisting of the two antennas and a second two-port network consisting of the first and second resonators in parallel approach zero as well as reflection coefficients of each port of the whole network are minimized.
