3D-printed λ/4 phase plate for broadband microwave applications

Abstract:

An efficient design for a quarter-wave (λ/4) retardation plate (QWP) operating at microwave frequencies has been designed and manufactured using dual head fused deposition modelling (FDM) 3D printing. Exploiting a bespoke composite material feedstock filament with high dielectric permittivity ϵr = 10.8, the resulting 3D-printed QWP comprising alternative layers of high and low permittivity had a high artificial double refraction of Δϵ = 2.9. The QWP provided broadband conversion of linear to ...
