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.
