Abstract
Superconducting electrically small monopoles and half loops over lossy groundplanes with perfectly conducting disks attached to their bases are modeled using a moment method incorporating Sommerfeld-type integrals. It is shown that improved efficiency is obtainable by incorporating these disks, compared with cases where the antennas are connected directly to the groundplanes
