The document lists various spiral antenna designs and their corresponding simulation methods, including coaxial fed single arm, rectangular, vivaldi, and two arm circular spiral antennas. It provides their performance metrics such as operating frequencies, gain values, and the simulation methods used (FEM and FDTD). Notable results include a gain of 6.5 dBi for the single arm spiral antenna at 10 GHz and 1.2 dBi for the rectangular spiral antenna.
