| Abstract(in English) | National Institute of Information and Communications Technology (NICT) has been currently researching and developing the next-generation communication satellite that flexibly changes the coverage using the Digital Beam Former (DBF) and increases the capacity using the Ka band array fed reflector antenna. In order to accurately form the desired beam on the DBF array fed reflector antenna, the systematic error calibration technique of array feed is very important because the Ka band has a very short wavelength. We have been proposed the self-calibration system using pickup antenna and gating process to realize a more accurate calibration method for array fed reflector antenna. The proposed method obtains the calibration values from the coupling characteristics with pickup antenna using gating processing. This paper shows the dependence of the proposed method on frequency. |
