Abstract
An antenna arrangement has radiation modes for antennas distributed across a geometrical shape, which is a bounded volume in three dimensions or a conformal surface of the bounded volume. A signal network couples between an electrical signal and the antennas with a taper along a selected dimension selected from the three dimensions of the bounded volume. The taper is specified by a selected dimension and a selected mode, which is selected from the radiation modes. Basis polynomials are indexed over the radiation modes and a specified basis polynomial is indexed at the selected mode. The specified basis polynomial gives the taper of an amplitude of the electrical signal at each of the antennas. An operating method determines a respective array factor for each distinct combination of one of the three dimensions and one of the radiation modes, and then selects the distinct combination with a desired array factor.
