A dual-band quad-polarized transmitarray (TA) is designed in a common aperture operating at 25.9/39.8 GHz. Using narrow strip patches as cells, the 25.9 GHz cells are arranged ±45° direction, and 39.8 0/90° direction formed square gap of to realize compact design with four polarization directions. In each band GHz, proposed TA dual-polarization designed. Measurements show that expected beams ca...

Office of Naval Research (ONR) of U.S.A navy has been carrying out research about advanced multifunction radio frequency concept (AMRFC) to apply the Multifunction Electronic Warfare & Electronic Support (MFEW ES) system to the future navy battleship [1]. In order to that conventional radar and communication antennas need to be active phased array antennas that can provide multi-functions such ...
