Abstract
A phased array antenna structure has a distribution network, and a composite of feed, module, and antenna honeycomb structures. The distribution network distributes or collects electromagnetic (EM) energy. The feed honeycomb structure is positioned adjacent the distribution network and connected to receive the EM energy from the distribution network or to distribute EM energy to the distribution network. The module honeycomb structure is positioned adjacent the feed honeycomb structure so as to receive EM energy from the feed honeycomb structure or to transmit EM energy to the feed honeycomb structure. The antenna honeycomb structure is positioned adjacent the module honeycomb structure on a side opposite the feed honeycomb structure so as to receive EM energy from the module honeycomb structure or to transmit EM energy to the module honeycomb structure. Each of the feed, module and antenna honeycomb structures have a plurality of aligned waveguides for transmitting EM energy therealong. The module honeycomb structure includes an electronic module for each waveguide wherein each electronic module has an electronic element for adjusting at least the phase of the EM energy and transmitting the adjusted phase EM energy to the aligned waveguide of the antenna honeycomb structure or the feed honeycomb structure.
