Applying HTS to microstrip patch antenna, one of the most difficult problems is the impedance matching at feed point. For good impedance matching, exact solutions of input impedance must be calculated. In this paper the solutions of it were presented. To do this, using Moment method based on Ground dielectric slab Green function, we calculate the current distribution and the real part and imaginary part of input impedance.

In this paper, a comparative study between superconducting microstrip antennas and gold antennas is reported in terms of the return loss, the characteristic impedance, efficiency and other various characteristics. HTS thin films used in this work were fabricated on YBa_2Cu_3O_7-x(YBCO)/MgO substrate. Superconducting microstrip antennas used in this work is that the feed line was directly inset a microstrip transmission line into 50 Ω region of the radiating patch. Measurements from HTS antennas and gold antennas showed that usable antennas could be made by using this architecture.
