摘　　要：为了解决对称振子圆极化天线工作带宽窄、不易实现宽频工作的问题,利用低通滤波器的特性,以实现天线宽频带工作为目的,提出了一种将对称振子天线的辐射振子与低通滤波器串联成一路辐射振子的方法,实现了一副天线在VHF频段、UHF频段及L频段3频同时以圆极化方式工作,大大提高了对称振子天线工作带宽;同时采用螺旋加载方式,实现了天线小型化设计的目的,通过仿真设计以及天线实测结构验证了所提方法的有效性。In order to solve the problem of narrow bandwidth of dipole antenna,a method utilizing the characteristics of low-pass filter is proposed,which connects a low-pass filter with a radiation dipole to implement an antenna that operates simultaneously in VHF,UHF and L bands.Spiral loading is used to implement the antenna miniaturization design.Finally,the effectiveness of the proposed method is verified by the simulation design and the test results.
