微波沥青路面除冰斜角辐射喇叭天线设计

 为拓展微波加热的应用领域，对微波路面除冰进行了研究。为使辐射天线与沥青负载近距离达到较好匹配，改善加热区域，减少波导阵列的加热盲区，设计了矩形口径喇叭。在此基础上，还设计了带有不同倾斜角的斜角喇叭，测试了斜角喇叭天线在沥青混合料为加热负载时的驻波比，做了实际的加热对比实验。对实验结果进行了分析，得到不同斜角喇叭在沥青料加热中的性能和使用高度,发现15°斜角喇叭符合微波除冰等近距离加热要求。

Design of sloped horn antenna for microwave deicing of asphalt pavements

To extend microwave heating applications,researches of microwave deicing have been done.The rectangular horn antennas were designed to match the load of asphalt admixtures,to improve the heated areas and decline unheated areas effectively.Horns autennas with different slopes are designed for numerical analysis and experiment.In the experiments,the input voltage standing wave ratio of these antennas were measured and the contrasts of effects were made after the asphalts mixtures were heated for the same time.The data was analyzed for better use of these horns,and finally the horn antenna with slop angle of 15 degree was detected to fit the request of near asphalt mixtures heating well in deicing.
