Abstract:
1. A millimeter-wave (MMW) communication system comprising: a transmit subsystem for providing signals to a plurality of transmit antenna elements; and a receive subsystem for receiving the signals from a plurality of receive antenna elements; wherein the transmit and receive antenna elements are physically arranged so that each of the receive antenna elements receives the signals transmitted from all of the transmit antenna elements with differing degrees of phase shift, and wherein: for a given one of the transmit antenna elements, a one of the receive antenna elements is a corresponding antenna element which is positioned directly across from, aligned with, and aimed at the given one of the transmit antenna elements, and the remaining receive antenna elements are non-corresponding antenna elements; there is an overall link length (L) between the transmit antenna elements and the receive antenna elements; there are direct link lengths (L the cross-link lengths (L
