Abstract
A flat microwave antenna comprising a network of emitting or receiving elements constructed by means of the printed circuit technique on a dielectric support. The elements are arranged on a series of radii (A to H) and are relatively equidistant on each of these radii. In the simplest construction, the radii are equiangularly spaced and the number of elements per radius is equal to 2.sup.n, n being a positive integer proportional to the length of each radial segment.
