中文摘要：
介绍了一种利用逆开环谐振器实现微带天线谐波抑制的方法。在传统逆开环谐振器的开口处添加一对缝隙,可有效的降低传输零点的位置。提出了加载逆开环谐振器微带线的等效电路模型,电路模型结果与仿真结果相吻合,证明了所提电路模型的正确性,并从等效电路模型的角度分析了传输零点下降的原因。将不同传输零点的结构单元级联起来制作在微带线的接地板上,很好地实现了微带天线的谐波抑制。仿真结果与测试结果相吻合,证明了所采用方法的有效性和正确性。该设计方法结构紧凑,简单易行。
英文摘要：
A method of harmonic suppression for microstrip patch antennas with complementary split ring resonators is presented.Lower transmission zero can be realized by loading a pair of narrow slots in the gap of the ring.An equivalent circuit model of the structure is given,and the model is verified by the simulation results.And the decline of the transmission zero is analyzed from the equivalent circuit model.With the units of different resonant frequencies in series,suppression of the hamonics can be realized for the microstrip antenna.The antenna is fabricated and measured.It is in good agreement between simulations and measurements,which verify the correction of the design.The structure is compact and the method is simple.
