Gaussian optics lens antennas
Abstract
Lens antennas (GOLAs) designed on the basis of Gaussian beam analysis differ from traditional horn lens systems in that the lens is completely separate from the feedhorn. It is shown that analysis in terms of Gaussian beam quasi-optical propagation permits great flexibility in design for obtaining highest gain for a given aperture size, lowest sidelobes, or any desired tradeoff. Data on GOLA design and performance are summarized; particular attention is given to the principal plane patterns of a GOLA operating at 94 GHz. Finally, mention is made of GOLA applications, including broad beam radiometry, mm-wave communications, and microturbulence detection.
