Abstract: A feed network for coupling elements of a multi-element patch antenna to transmit or receive circuitry may include segments having dimensions that maximize the impedance of the feed network. Increasing the feed network impedance can simplify matching of the feed network to conventional transmission line impedances (e.g., 50 Ohms, 75 Ohms), which reduces reflections of the operating signals as a result of impedance mismatches. By designing the feed network as a hierarchical distribution network of transmission lines of particular lengths selected to maximize impedance, signal reflections may be reduced and bandwidth of the antenna system may be improved.

Abstract: A method and apparatus for communicating simultaneously at the same frequencies includes two or more conductor-backed, spiral antennas that have been shown to exhibit linear polarization. To permit simultaneous transmission on the same frequencies, two of the linearly polarize, conductor-backed spiral antennas can be spaced vertically and be oriented so that the feed points of one antenna are orthogonal to the feed points of the second antenna. Since the specifically designed spiral antennas will be both transmitting or both receiving at orthogonally arranged polarizations, the antennas will not interfere with each other, even though communication is upon substantially the same frequencies.
