| Abstract: | A 2GHz circularly polarized copper microstrip antenna and a 4.5GHz circularly polarized YBCO microstrip antenna are designed and fabricated.The copper microstrip antenna has a beam-width of 63° and an axial ratio of 1.2dB.The superconducting YBCO antenna has about 3dB gain improvement over the comparable silver antenna at 77K.The beam-width of the superconducting antenna will be larger than 63°,which will make circularly polarized YBCO microstrip antenna more praticable in some space communication fields. |

| Keywords: | circularly polarization microstrip antenna HTS(high temperature superconductor) |
