Design of Array Antenna for High-Strength Radiation Field Generation at k-Band

The high-strength radiation filed is characterized by a wide frequency range and high intensity of the electric field, which will cause great harm to the normal operation of the ship's electronic and electrical equipment. In order to verify the high-strength radiation protection ability of the equipment, we design a type of array antenna that can generate the field strength meeting the GJB 1389A standard at k-band. In the form of array antenna, the output of the power amplifier to each antenna can be reduced to improve the reliability to the system, and on the other hand, the synthesis efficiency of the system is improved by the space synthesis compared to the channel synthesis.
