玻璃因其光滑的表面和出色的均匀性而在射频应用中具有优势。在频率高于 30GHz 的毫米波范围内，玻璃的优势变得更加重要。在本文中，我们讨论了一种新型玻璃的特性，这种玻璃特别适合作为高增益、高带宽毫米波天线和滤波器结构的基板。我们在这项工作中将这种新型玻璃称为 SCHOTT 8325，其介电损耗比标准无碱玻璃的介电损耗低 3 倍，并且介电常数较低，为 $epsilon^{prime}=4$。我们讨论了这种玻璃在毫米波天线和滤波器应用中的适用性，并展示了频率高达 110GHz 的介电损耗的测量数据。该材料在高频下的 Qf 值约为 18000 GHz。
Glasses have advantages in RF applications due to their smooth surfaces and their excellent homogeneity. The advantages of glass become more important in the range of mm-waves for frequencies above 30GHz. In the current paper we discuss the properties of a new glass which is in particular suited as a substrate for high gain, high bandwidth mm-wave antennas and filter structures. The new glass, which we call in theis work SCHOTT 8325, has a dielectric loss which is lower than the dielectric loss of standard alkaline free glasses by a factor of 3, and has a low dielectric constant of $epsilon^{prime}=4$. We discuss the applicability of such a glass for mm-wave antenna and filter applications and show measured data of the dielectric loss for frequencies up to 110GHz. The material shows a Qf value of around 18000 GHz at high frequencies.
