Advanced antenna measurement topics

Abstract

This chapter encompasses a number of disparate antenna measurement topics: open-ended rectangular waveguide probes; dual polarised waveguide probes; broadband probes; far-field anechoic chamber measurements; probe calibration; channel balance correction for measurements of linearly and circularly polarised antennas; aperture diagnostics; amplitude and phase drift correction; antenna pattern rotation; alignment correction in planar antenna measurements; antenna pattern correction; near-field antenna measurements; planar and cylindrical mathematical absorber reflection suppression; spherical near-field electrical alignment; and three antenna gain method.
