This book approaches the antenna measurement tasks at millimeter wavelengths, with focus on a particular antenna measurement system: the compact range. Several techniques are described, covering analysis, design and assessment. The proposed methods follow the sequential steps involved in the tests of an antenna. First contributions cover the Electromagnetic analysis, proposing two hybrid formulations which offer complementary points of view about the ranges study. These algorithms are used to reach design conclusions on the ranges field collimator. Also, the assessment stage is studied at...
