摘要：
Various embodiments are described that relate to patch antenna elements and parasitic feed pads. A patch antenna element can have a resistance and reactance. The resistance can be desirable while the reactance can be undesirable. To counteract the reactance, a parasitic feed pad can be placed near the patch antenna element and the parasitic feed pad produces a capacitance. The capacitance balances out the reactance to cancel out one another. When two patch antenna elements and two parasitic feed elements are employed in one antenna stack, the stack antenna can function as a dual band antenna.
