| Abstract;As a method of the active phased array antennas using the synchronization, this paper examines the behavior of phased array which has locking sources at both ends and is controlled by the phases of the injection signals. Though this system has multiple operating modes, mode jumps can be suppressed by shifting the free-running frequency of the end element in the array. The condition of mode unification is obtained by the approximate analysis of the behavior equation, and the effectiveness is confirmed by the numerical calculation. The experiments which scans radiation beam of the 2,3,5 elements antenna arrays using an active integration antenna composed of a patch antenna and serial feedback type FET oscillator are conducted, and the results show that the directional scan field expands by making it to be a single mode behavior. |
