3D-printed low-cost, low-loss microwave components up to 40 GHz

This contribution investigates the manufacturability and the performance of waveguide components fabricated using a consumer-grade 3D printer. This low-cost process enables a fast fabrication of microwave circuits almost directly from a 3D simulation model to a ready-to-use component. Two different components, a simple waveguide and a more complex array with integrated power combiner, are manufactured and characterized to validate the approach.
