摘要
本文设计并研制了 2GHz敷铜板圆极化微带天线及 4 5GHz高温超导 (HTS)圆极化微带天线 .2GHz敷铜板圆极化微带天线的半功率角为 6 3° ,最好轴比为 1 2dB ;4 5GHz的HTS圆极化微带天线相对于银天线有 3dB的增益改善 ,其半功率角大于 6 3°.
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.
