Abstract

A method based on Hilbert-transforms is used to reconstruct phase, group-delay and impulse response from magnitude-only information regarding the S₁₁ and S₂₁ parameters of electromagnetic bandgap structures constructed by periodically etching the ground plane of a microstrip line. Simulations and measurements show that for many practical cases this allows to fully characterize the devices with a simple scalar network analyser instead of more sophisticated instrumentation, such as a vector network analyser
