摘要: 该文介绍了一种性能优良的四元U型缝贴片天线阵。该阵面由一新型的宽带匹配网络馈电,能量通过地板上的馈电缝耦合到上面的U型缝贴片上。这种类型的天线阵可以在10.4-16.7GHz的频率内工作,阻抗带宽达46.5%,最大增益为15dBi,增益在13dBi以上的频率范围达30%,交叉极化电平在整个频带内均小于-18dB。Abstract: A new antenna array consisting of U-slot microstrip patches is introduced. The array is fed by a novel wideband matching network and the energy is coupled to the U-slot patches through the feed slot on the ground. The operating frequency range of antenna array is from 10.4 to 16.7GHz, corresponding to an impedance bandwidth of 46.5%. The gain is above 13dBi from 11-15GHz.
