Abstract

Due to the ground plane effect, the horizontal omnidirectional pattern of the monopole antenna will tilt upwards, thereby affecting the communication quality in the horizontal direction. In this paper, one composite structure (CS) composed of mushroom structures (MSs) and parasitic metal pillar elements (PMPEs) is introduced, loading uniformly around the source antenna (SA) to suppress the beam upwarping. The individual MSs can enhance the current on the ground plane, coupling more electromagnetic energy to the horizontal plane in the band outside the bandgap. Meanwhile, the PMPEs act as directors, guiding the space wave energy along the horizontal plane in a wide band. By using the two structures as one CS together, beam upwarping suppression is realized for the monopole antenna in broad bandwidth. This structure can achieve 4–25° of suppression at 410–522 MHz and 0.97–2.3 dB improvement on the horizontal plane gain, which is much better than the condition when the two structures are loaded alone. The experimental results prove the theoretical analysis. This structure can provide more stable communication for the design of high-performance devices.

利用复合结构抑制宽带水平全向单极天线的波束上凸

由于地平面效应，单极天线的水平全向图会向上倾斜，从而影响水平方向的通信质量。本文介绍了一种由蘑菇结构（ms）和寄生金属柱单元（PMPEs）组成的复合结构（CS），该结构在源天线（SA）周围均匀加载以抑制波束上移。单个MSs可以增强地平面上的电流，将更多的电磁能耦合到带隙外的水平面上。与此同时，PMPEs起到了导演的作用，引导空间波能量沿水平面在一个宽频带内运动。通过将两种结构作为一个CS组合使用，实现了单极子天线在宽频带下的波束上行抑制。该结构在410 ~ 522 MHz时可实现4 ~ 25°的抑制，水平面增益提高0.97 ~ 2.3 dB，大大优于两种结构单独加载时的效果。实验结果证明了理论分析的正确性。这种结构可以为高性能器件的设计提供更稳定的通信。
