Description
To determine the relative permittivity $\epsilon_r$ and the dielectric loss factor $\tan(\delta)$ of 3D printed polymers at 500 MHz a dedicated test cavity was built. When a dielectric material is inserted, the frequency and the quality factor of the cavity change. A comparison of the measured data with simulations yields the values of $\epsilon_r$ and $\tan(\delta)$. This allows the use of these 3D printed polymers in RF applications such as power couplers or RF windows.
