Abstract

A radio-frequency coupler was designed and implemented using high-temperature superconductor (HTSC) YBCO films. A circuit for a single superconducting coupling channel was implemented and serves as the primary component in the multichannel coupling system geometry, allowing a high-power broadcast due to low losses of superconductors below the critical temperature (T_c). In this paper, a solution for the multiple antennas' isolation problem is proposed by reducing the number of antennas to a single antenna. Multichannel transmission systems require high-power broadcasts in order to transmit signals over long distances. A coupling system with low losses was used to improve the system's active performance. In this paper, the system is implemented in a very high-frequency range using a microstrip in meander geometry.
