【摘要】 本文设计了一种中心馈电的印刷条带状天线,通过条带两端加载不同类型的销钉引导条带馈点两侧电流同向流动,以实现天线的法向最大辐射。因天线条带状,因此既可通过曲流技术降低天线谐振频率实现小型化,又很容易通过多条带共馈点排布实现多频工作。通过上述方法设计的一个双频条带天线,工作频率为4.66GHz和6.92GHz,低频段增益4.8dBi,高频段增益6.6dBi。天线尺寸仅约为0.46倍高频波长。该方法设计实现的天线不仅便于小型化和各谐振频点的独立调节,而且加工方便,成本低廉。更多还原

【Abstract】 In this paper,a center-fed printed strip antenna is designed.By loading different types of pins at both endpoints of the strip,the current on both sides of the strip feed point is guided to flow in the same direction to achieve the maximum normal radiation of the antenna.Because the antenna lines are banded,the resonant frequency of the antenna can be reduced by meandering technology to achieve miniaturization,and the multi-frequency operation can be easily achieved by the arrangement of multi-band common feed points.A dual-band antenna designed by the above method operates at 4.66GHz and 6.92GHz,with a low frequency gain of 4.8dBi and a high frequency gain of 6.6dBi.The antenna size is only about 0.46 times of the high-frequency wavelength.The antenna designed and realized by this method is not only convenient for miniaturization and independent adjustment of frequency points,but also convenient for machining and low cost.更多还原
