Microwave antenna holography

IEEE Transactions on Microwave Theory and Techniques, 1992
The application of the holography technique to the newly constructed NASA/JPL Deep Space Network (DSN) 34-m beam-waveguide antenna, resulting in 4.1-dB performance improvement at 32 GHz by reducing the main reflector RMS surface error at 0.43 mm, is described.

Large antennas and microwave antennas

2005
Large antennas and microwave antennas, which form the subject of the remaining chapters of this book, are characterized by the property that their useful dimensions are very large compared with the wavelength involved. The word ‘large’ refers to the physical dimensions of the antenna (radio telescopes, for example) compared with which the wavelengths ...

Microwave Antenna Measurements

Proceedings of the IRE, 1947
A description is given of the techniques involved in measuring the properties of microwave antennas. The measuring methods which are peculiar to these frequencies are discussed, and include the measurement of gain, beam width, minor lobes, wideangle radiation, mutual coupling between antennas, phase, and polarization.
