摘要 <p>A shaped article having a shape suitable for use as an antenna in which the material from which the antenna is constructed becomes electrically superconducting at a temperature which is not lower than the temperature at which liquid nitrogen boils. The material may be a ceramic material, for example an oxide material, eg YBa2Cu3Ox where x is between 6.5 and 7.2</p>
