Abstract
Periodic variations in the field intensity across a radiating aperture are investigated, and it is shown that they may alter the shape of the radiation pattern and reduce the power gain of the aperture. The way in which such variations arise in the distribution existing across the outer surface of a microwave lens is discussed.Keywords
