Active Superconducting Electrically Small Antennas: Design Issues of Basic Cells

We discuss design issues and present Nb-based layout designs of two basic cells for broadband active electrically small antennas based on superconducting quantum arrays. The cells are the differential array circuit and bi-SQUID. The cell layouts realize parameter values answering results of the in-depth theoretical analysis performed earlier for attaining the high-linearity voltage response to magnetic signal. The layouts are to give reference approaches to the antenna circuit designs to be fabricated using niobium process.
