A superconducting slot antenna combined with a bandpass filter composed of coplanar waveguide meanderline resonators has been designed and tested. Based on a new design theory for broadband impedance matching circuits, we designed a slot antenna with a small radiation resistance of 1 Ω impedance matched to a three-pole Chebyshev bandpass filter with 10 GHz center frequency and 0.35% fractional bandwidth. Experiments with a YBCO slot antenna on a MgO substrate have demonstrated the designed performance.
