摘　　要：基于复合左右手传输线的零阶谐振理论,优化设计并加工制备了一种具有全向辐射性能的X波段新型低剖面微带天线.仿真结果表明,此类天线全向辐射均匀性良好,回波损耗测量和仿真结果一致.该天线具有低剖面和全向辐射的优点,可以加载在车辆和飞机等移动载体上,满足实际通信的需要.Based on the zeroth-order resonance theory of the composite right/left-handed transmission line. a new type of low-profile omnidirectional microstrip antenna operating at X- band is presented. From the simulated results, the proposed antenna can omnidirectionally radiate well in a horizontal plane at its operation frequency. The good agreement between the measured return loss and simulated one is obtained. With the characteristics of low-profile and unique radiation manner, the antenna can be used in vehicle-mounted and flight-mounted carriers etc. for communication.
