Material Characterization at Millimeter Wave Frequencies in TUBITAK UME

Erkan Danaci, Emre Cetin

Abstract

The frequency response of the materials which are used in milimetre wave communication system has gained increasing importance nowadays. Frequency response measurement of materials in laboratory environments do not contain sufficient information about real working environment conditions. Free space, known as one of the most frequently used material characterization method at high frequencies, is used to give more accurate results under real operating conditions. In this study, using the TUBITAK UME’s infrastructure, the measurement results in free space and the uncertainty calculations of the measurements are given for some materials such as teflon, fr4, air, komacel. Measurements were performed at 67 GHz to 115 GHz and 110 GHz to 170 GHz frequency bands by using KMMS software which is known run up to 50 GHz frequency . Measurement results of materials were compared with known low frequency response of the materials in this study.
