1. An antenna comprising:
a plurality of antenna modules tiled together and configured to form one metasurface antenna with an array of surface scattering metamaterial antenna elements;
a feed network comprising a plurality of feed points coupled to the plurality of antenna modules, each feed point of the plurality of feed points to supply one of the antenna modules with a feed wave;
a digital combiner coupled to the plurality of antenna modules to digitally combine signals from the plurality of antenna modules; and
an analog divider network to divide transmitted power among antenna modules in the plurality of antenna modules.
