Abstract

This paper presents the microwave characterization of NinjaFlex 3D-printing filament using Keysight 85070E Perfor-mance Probe. The electromagnetic properties (dielectric constant and dielectric loss factor) of the NinjaFlex are measured from 200 MHz to 20 GHz, and its loss tangents values (\tan\delta) are calculated accordingly. The results are compared with previously reported techniques based on ring resonator and Keysight N1501A High Temperature Dielectric Probe. To investigate the application of NinjaFlex filament for antenna manufacturing, a triangular edge-fed patch antenna is designed and simulated based on the measured electromagnetic properties. To examine the antenna's potential for wearable applications, numerical and experimental tests are conducted on its performance under structural de-formation such as bending and in proximity of human body. The reflection coefficient of the fabricated antenna are measured in flat and bent conditions and the results are presented and compared with the simulation.
