EuCAP 2019 – European Conference on Antennas and Propagation
EuCAP is one of the leading conferences on antennas and propagation, attracting researchers from across the world. With approximately 1200 to 1500 attendees, it is one of the largest conferences of its type. Welcome to Premix's booth to see our ultra-low loss, dielectric PREPERM® plastic material for antenna applications!

In this paper, we have characterized dielectric properties of low-loss radome materials with three different measurement methods, at microwave and mmWave frequencies. The techniques include an over-the-air (OTA) far-field measurement at 55-95 GHz, a Fabry-Perot open resonator (10-60 GHz), and a split-post dielectric resonator whose empty resonance frequency is 2.45 GHz.
Both resonator methods give very similar values for the dielectric constant and loss tangent, but the OTA measurement overestimates the dielectric constant by 8% and has larger variation between loss tangent values of different materials. Finally, it is evaluated how uncertainty in dielectric properties affect the radome performance.
