Abstract

The electrical characteristics of various elements that can be used as spatial phase shifters in circularly polarised (CP) reflectarrays are contrasted. The elements investigated are; a single rotating dipole at 10.3 GHz; a multiple dipole at 18.2 GHz; a rotating stub at 2.8 GHz; and a periphery point short-circuited circular patch at 3.0 GHz. For each element type, results are presented for the reflection phase, polarisation purity and reflection loss. Where appropriate, experiments are performed using the waveguide simulator technique to validate the numerical EM simulation.
