Glass-Ceramic as a High-Performance Antenna Material

Glass-ceramics are known for their extremely low losses of electromagnetic radiation. Hubertus Braun (26), a young researcher and doctoral candidate at SCHOTT has now been presented with a grant in the area of natural and engineering sciences worth 5,000 euros from the Vodafone Foundation for the paper he wrote at SCHOTT in cooperation with the Johannes Gutenberg University in Mainz.



Especially in the area of satellite navigation, mobile communications and microwave electronics, the demand for materials for antennas in the gigahertz region and the respective high-frequency filters has risen in recent years. While doing his research at SCHOTT, physicist Hubertus Braun managed to produce an extremely homogeneous, non-porous antenna material that offers important advantages in terms of key quality attributes, for instance miniaturization, higher efficiency and lower susceptibility to interference, compared to the ceramics used in the past. The technology company has already started performing industrial research based on the results of his research work for which SCHOTT has already filed for a patent.



From the kitchen to the cosmos, SCHOTT is the global leader in the area of glass-ceramics. CERAN® brand glass-ceramics have been conquering kitchens all over the world already since 1973. And, with nearly zero thermal expansion, ZERODUR® glass-ceramic has served as the standard material for use in mirror substrates for the world's most powerful astronomical telescopes for over four decades. The commercialized know-how that has been amassed on this temperature-stable material in these areas is constantly further developed in SCHOTT’s research laboratories and offers options for many fields of the future, as these latest results clearly show.



SCHOTT is an international technology group with more than 125 years of experience in the areas of specialty glasses and materials and advanced technologies. SCHOTT ranks number one in the world with many of its products. Its core markets are the household appliance, solar power, pharmaceuticals, electronics, optics, transportation and architecture industries. The company is strongly committed to contributing to its customers’ success and making SCHOTT an important part of people’s lives with high-quality products and intelligent solutions. SCHOTT is committed to managing its business in a sustainable manner and supporting its employees, society and the environment. The SCHOTT Group maintains close proximity to its customers with manufacturing and sales units in all major markets. Its workforce of around 17,000 employees generated worldwide sales of approximately 2.9 billion euros for the 2010/2011 fiscal year. SCHOTT AG, with its headquarters in Mainz (Germany) is owned by the Carl Zeiss Foundation.
