1. An antenna for operation across multiple frequency bands, the antenna comprising, in order,
a ground plane;
a first conductive member separated from the ground plane;
a pair of second conductive members forming, with the first conductive member, a resonant structure sized to resonate at a higher frequency band of the multiple frequency bands; and
a pair of third conductive members forming a resonant structure sized to resonate at the higher frequency band of the multiple frequency bands,
wherein the first conductive member is sized to resonate at a lower frequency band of the multiple frequency bands.
