A radiation assessment apparatus applicable to mmWave antennas based on a 2D scanner

Advances in solid state technology have helped realizing wireless communications using millimeter waves and so does the need for antenna measurement in this band. This paper reviewed several antenna measurement range designs. Their pros and cons are studied. A measurement apparatus, which is crafted to co-work with large, heavy mixer modules of an E-band network analyzer, was proposed. The measurement range contains a 2D scanner, which takes samples on a planar surface in the farfield. Collected data can be transformed to provide antennas' farfield patterns. Preliminary experiments were taken in the X-band to verify the effectiveness of the proposed measurement configuration.
