A Fast Method for Optimization and Design of Frequency Reconfigurable Microstrip Antenna

For changing the status that optimization and design of frequency reconfigurable microstrip antenna recently is usually depended on repeated experiments, an efficient and fast method is proposed in this paper. A Novel Quantum Genetic Algorithm (NQGA) is combined with universal spatial MoM in the proposed method and calculating time is saved by using Direct Matrix Manipulation (DMM) technique used in computing Z-matrix. Using this method, a frequency reconfigurable cylindrical conformal microstrip antenna is obtained that can work at ten or more narrow frequency-bands. Comparing the optimization results in the paper with commercial software results shows that the method in this paper is correct and efficient.
