Abstract
A hearing device includes first, second, and third antennas oriented respectively along first, second, and third axes that are different from one another. The device includes first channel circuitry coupled to transceive and process antenna signals of each of the antennas. The antennas and the first channel circuitry communicate with another hearing device via a near field magnetic induction (NFMI) signal through a first near field magnetic induction (NFMI) communication channel. Second channel circuitry is coupled to transceive and process the antenna signals of each of the antennas. The antennas and the second channel circuitry communicate with the other device via the NFMI signal through a second NFMI communication channel. Third channel circuitry is coupled to transceive and process the antenna signals of each of the antennas. The antennas and the third channel circuitry communicate with the other device via the NFMI signal through a third NFMI communication channel.
