Commutation switches for electronically scanning cylindrical arrays are disclosed. One embodiment reduces the number of transfer switches needed in a commutation switch by utilizing the commutation inversion property inherent to transfer switches having a binary number of input and output ports. A second embodiment having inversion capability provides a transfer switch with non-binary number of input and output ports. Commutation switches employing transfer switches of the second embodiment exhibit reduced complexity over the prior art and provide lower signal loss than that achievable with commutation switches of the prior art.
