| Abstract(in English) | A beam tracking concept and its principle are proposed in this paper. By using this principle, a new beam tracking antenna which consists of a magic-T circuit, two antenna elements and two phase shifters has been designed. The main concept of the proposed antenna is to shift the beam by adjusting the phase shifter using the difference of signals received by the two antenna elements. Theoretical results assuming the antenna as isotropic are described to explain the concept. Both-sided MIC technology is completely used to integrate the magic-T and phase shifters with a simple structure. Radiation patterns are measured and this concept is experimentally demonstrated. The simulated and experimental results of the relation between arrival angle and bias voltage are also compared successfully. The beam tilts to 22 and 19 at the phase shifter bias voltage of 9 V in simulation and experiment, respectively. |
