ABSTRACT:
An array antenna for use in, e.g., a radar includes a plurality of pairs of vertical polarization antenna elements and horizontal polarization antenna elements. A particular transmission/receipt module is connected to each pair of vertical and horizontal polarization antenna elements. A beam controller forms a transmission/receipt digital beam while a local signal generator controls a transmission/receipt frequency. The beam controller is connected to the transmission/receipt modules via a data bus and I/O (Input/Output) sections included in the modules.
