Abstract :
The improvement in efficiency that is possible by replacing the normal conductors in an electrically small antenna with high-temperature superconductors (HTSs) is assessed. The transmission line size parameters were selected as sizes that are practical for antennas in the 100 MHz to 1 GHz frequency range and that would give a 50 Omega impedance with a reasonable value of the dielectric constant. The antenna and matching network considered, in addition to being a feasible configuration for a practical HTS antenna, also serve as a surrogate for other electrically short antennas.<>
