We developed a single-chip receiver antenna combined with coplanar waveguide (CPW) impedance matching circuits and multi-bandpass filters (multiplex receiver). Firstly, we designed a HTS slot antenna with 10.5 GHz center frequency. Next, in order to compensate the reactance of the antenna at different center frequencies of the BPFs, we attached the reactance compensation transmission lines behind the Y-junctions. Finally, we design the channel #1 BPF and channel #2 BPF matched to the input impedance of the antenna and reactance compensation line. The channel #1 BPF has center frequency = 10.3 GHz and channel #2 BPF has center frequency = 10.7 GHz. The prototype YBCO 2-channel BPFs was fabricated and verified the design theory.
