As an RF high Tc superconducting (HTS) front end for a microwave receiver, we propose a new design method for the broadband matching circuit composed of coplanar waveguide (CPW) meanderline resonators connecting a slot antenna with CMOS low noise amplifier (LNA). The parameters of the antenna sections with matching circuit are calculated and simulated with the circuit simulator and electromagnetic field simulator. CMOS LNA was designed and its input and output impedances and noise figure were obtained by SPICE simulation.
