Near-high frequency antenna for unmanned aerial system ice-penetrating radar

In this letter, we present the novel design of a near-high frequency antenna for a small unmanned aircraft systems helicopter for the intended purpose of sounding and imaging temperate glaciers. The antenna leverages concepts in the areas of efficient electrically small antennas, structural antennas, and impedance matching to create a versatile design that is small and lightweight yet robust for airborne operations and has wider bandwidth than existing designs.
