Experimental assessment and compensation of the interaction between modulated probe arrays and antenna under test in cylindrical rapid near-field measurements
Experimental assessment and compensation of the interaction between modulated probe arrays and antenna under test in cylindrical rapid near-field measurements A.Ziyyat(l) , D.Picard(2), J.Ch.Bolomey(2) Abstract Rapid near-field measurements can be performed by using a probe array instead of mechanical scanning a single probe. However, among possible objections against using probe arrays, the inte
