Abstract

A metal waveguide feed chain in a Ku-band scanning lens array antenna comprises 5 parts. These are: two iris polarisers, two bend-feeds, and a central power combiner. The combiner comprises a pair of septum polarisers and tee junctions. The feed chain generates a controllable, linear polarised E-field at each of two hemispherical lenses. Additive manufacturing was used to produce a copy of the power combiner and each bend-feed in copper plated plastic. In satellite receive-only trials at 10.7-12 GHz the plastic parts and metal parts performed equivalently.
