Abstract

Summary form only given. One of the drawbacks of using HTS (high-temperature superconductor) for microstrip antennas, is the fact that HTS is unavailable on low-permittivity substrates. The use of a high-permittivity substrate for microstrip antennas leads to undesirable characteristics such as narrow bandwidth and reduced radiation efficiency due to surface wave generation. To overcome this difficulty and effectively use HTS in microstrip antenna systems, a two-layered electromagnetically coupled microstrip patch has been investigated. This configuration allows the patch to be patterned with gold on a lower permittivity substrate while still using HTS for the feed network.<>
