Type of article: Article
Summary
The paper describes the design and reports experimental results for a two-element superdirective array antenna fabricated with YBCO superconducting material. The array antenna thus fabricated realized good impedance matching and higher radiation efficiency than a copper antenna, and a unidirectional radiation pattern at 80 K and around 900 megahertz.
