| Summary: | Laboratory methods of measuring the radiation characteristics of microwave antennas were investigated at a wavelength of 1.25 cm. The methods consisted of rotating the antenna in question in a microwave beam issuing from a collimating lens made from polystyrene plastic. With uniform illumination of the lens, diffraction from its edge caused severe departure of the beam from the plane wave desired for antenna measurements; inaccuracies in the measured antenna characteristics resulted.
