A spiral planar antenna includes more than two spiral arms. Each arm includes at least a portion that is coiled. The antenna may operate from approximately 50 MHz to upwards of several GHz within a payload space of only about 5.75 inches in diameter and less than one inch in height, with approximately 5 dBi or less of measured axial ratio. The broad frequency response in conjunction with a small space-profile improves space limitations and payload for deployable and non-deployable platforms while reducing opportunities for electromagnetic interference.
