Glasses and Glass Ceramics for Applications in High Frequency Electronics

We report on the applicability of glasses and glass ceramics in the field of high frequency electronics. The main argument for applying such materials in high frequency electronics is their excellent homogeneity, which allows to make designs with kHz accuracy in the range of GHz frequencies. The range of dielectric properties which are covered by glasses and glass ceramics is outlined. Further on a number of examples are discussed were either glasses or glass ceramics are used with antenna functionalities or for high frequency filter applications.
