【摘要】 以圆环天线作为馈源,开口谐振腔作为反射体,设计了一款工作频段为2 GHz的强定向圆环背射天线.对该款天线的输入阻抗进行了匹配,并进行了性能研究和实验测试,得到了具有增益高、前后比大、旁瓣电平较低、频带宽、馈电方便等优点的实用天线.更多还原

【Abstract】 Using the circular loop antenna as a feed source,the exoteric resonance cavity as reflect object,a strongly-directional circular backfire antenna was designed.The antenna’s working frequency was 2 GHz,and the input impedance was matched.The antenna was tested and studied.It had excellent applied performance:high gain,large ratio front and back,low power of the adjacency beam,large bandwidth,easy feed in power,and so on.更多还原
