Abstract
A three-dimensional spiral antenna includes a substrate, a spiral antenna element, and a feed point. The substrate includes a three-dimensional shaped region. The spiral antenna element is supported by and conforms to the three-dimensional shaped region such that the spiral antenna element has an overall shape approximating a three-dimensional shape. The feed point is coupled to a connection point of the spiral antenna element.
