Abstract :
The radiated fields due to a circular array of patch antennas are investigated. The aperture method is used to determine the fields of the patch; for this initial study, the effects of mutual coupling are not included. The dependence of the radiated fields on the array geometry is examined for a frequency of 10 GHz and a substrate dielectric constant of 2.2. The practical applications of this array configuration are of interest for radar systems and air and space navigation systems.<>
