Abstract

Ceramic (Ba_0.55Sr_0.45Ti_1.01O₃) – polypropylene polymer ER182 composites-based materials were applied for sub-THz range antenna lens application in telecommunications. Typical plano-convex -shaped lenses were simulated and measured with a standard rectangular waveguide at 220–330 GHz frequency band and applied on 150 mm on-air distance. The lens fabricated with ER182 polymer material increased the signal strength by 15 dB, ER182/7 vol% BST by 6 dB and ER182/30 vol% BST by −23 dB. Material loss tangent values were 0.008 for ER182, 0.034 for ER182/7%BST and 0.081 for ER182/30%BST. The directivity of ER182 material lens and WR3 waveguide combination was 26 dBi at 300 GHz.
