Claim:
1. A method for determining the geometry of a planar multi-focus array antenna for the Ka band comprising at least two antenna elements, each antenna element comprising a reflector and a sub-reflector, at least one source powering said antenna elements, the method comprising at least the following steps: defining a threshold value G representing the surface of the sub-reflector and the surface of the reflector by a set of points ((X generating from a suitable electromagnetic simulation module a set of pairs of values {(θ determining for each pair of values and from the pattern of an elementary source under consideration, the value of the maximum antenna gain in the direction of the array lobes, comparing the value of the maximum gain obtained, and if this value is above a threshold value, then varying at least one of the parameters ((X determining the shape of the antenna from the points verifying the threshold values.
