Abstract
This paper presents two solutions to improve the front to back ratio (FBR) of the VeraPhase® (VP6000) antenna. A compact and light disk structure and a ground plane with absorber layer located under the antenna were designed and optimized in the 3D RF simulator WIPL-D in order to reduce the FBR without impacting the other performances of the antenna. The optimized results show great improvement of the FBR at all frequencies from 2.5 dB up to 7.3 dB without reducing the gain in the upper hemisphere of the antenna. The proposed solution are both efficient and low cost solutions to optimize the FBR of the VP6000.
本文提出了提高VeraPhase®(VP6000)天线前后比(FBR)的两种方案。为了在不影响天线其他性能的前提下降低频响比，在三维射频模拟器WIPL-D中设计并优化了紧凑轻便的圆盘结构和天线下方带吸收层的地平面。优化结果表明，在不降低天线上半球增益的情况下，天线在2.5 dB ~ 7.3 dB范围内的频宽有了很大的提高。所提出的方案是优化VP6000快流比的高效低成本方案。
