Abstract
Satellites require a suitable antenna for line of sight microwave communication with the ground. Disclosed here is an Archimedean spiral antenna backed by a copper cavity containing quadruple conical perturbations. The antenna meets the required size, mass, transmitting power, bandwidth, and circular polarization for a satellite (e.g., CubeSat) environment while providing immunity to the mounting position.
