Adaptive Conformal Antenna Design And Research

The excellence of the microstrip antenna is it's conformal .As the development of technology , the use of conformal micropstrip antenna in plane and aviation aerocraft becoming more and more abroad.In this thesis, First , we introduced the basis theory of microstrip antenna. Then using the cavity model theory analyzed the variety of the conformal microstrip antenna's resonance frequency and input resistance .Using reciprocity theory compute the E face and H face's radiation pattern .Second ,according to the formula and practical need ,in the given frequency and medium constant ,deduced the practical formula for designing conformal microstrip antenna .Last ,using the super digital signal process chips and circuit design ,achieving adaptive signal process of the conformal antenna array.The coupling between conformal antenna array is very important .It influenced the radiation pattern and resistant of the conformal antenna. In this thesis, we use the full wave theory analyzed the coupling between common antenna array, then considering the influence of curvature in conformal antenna array , using full wave theory analyze the coupling between conformal antenna array computing the coupling result between E face and H face . discussing the influence of curvature and space between antenna cell in coupling. Last give some factual examples according to the formula in the thesis.
