An antenna may include a ground plane, a tuning stub, and a shorted spiral antenna element connected to the tuning stub. The shorted spiral antenna element may include a plurality of spiral traces shorted together by a shorting element extending radially outward to contact each of the spiral traces.

Spiral wideband low frequency antenna

One aspect of this disclosure provides an apparatus comprising a substrate portion and a radiating portion. The substrate portion comprises top and bottom surfaces, first and second substantially straight and parallel substrate edges, a third substantially straight substrate edge, and a fourth substrate edge having at least a curved portion. The radiating portion is disposed on the top surface of the substrate portion and is configured to radiate within a frequency range having a maximum frequency value of approximately 6 GHz. The radiating portion has first and second substantially straight and substantially parallel radiating edges, a third substantially straight radiating edge, a curved radiating edge, and a via that passes through the substrate portion and conductively couples the radiating portion to a terminal on the bottom surface. A portion of the curved radiating edge is effectively incident with air along at least the curved portion of the fourth substrate edge.
