Antenna Array Measurements by a Scalable Backscatter Modulation Procedure
Journal article, 2024
We introduce a novel measurement approach for characterizing antenna arrays based on the backscattering modulation method. Systematic retrieval of antenna parameters is achieved via a scalable S-parameter re-normalization procedure. Additionally, the frequently overlooked sign ambiguity in phase retrieval of coupling S-parameters is addressed. Numerical results for a four and eight-element dipole array demonstrate the effectiveness in extracting the S-parameters and gain patterns using only three switchable load terminations per antenna element
