摘要

在2.45 GHz工业、科学和医疗无线电波段,研究了传统平面倒f天线(PIFA)天线在邻近布局路径上的电磁耦合。本文报道了互补劈环谐振器(CSRR)在扰动地平面后对降低耦合和天线整体性能的影响。采用2.5D和3D全电磁仿真对所提出的布局进行了设计和分析。实验结果验证了CSRR在减小天线耦合方面的有效性。

Analysis of PIFA antenna coupling in nearby traces and reduction with CSRRs in PCB at 2.45 GHz
The electromagnetic coupling of a conventional planar inverted-F antenna (PIFA) antenna in the nearby layout traces is investigated in the 2.45 GHz industrial, scientific and medical radio band. The impact of a complementary split-ring resonator (CSRR) to reduce the coupling as well as the overall antenna performance after perturbing the ground plane is reported. 2.5D and 3D full electromagnetic simulations are used to design and analyze the proposed layouts. Experimental results validate the CSRR usefulness to significantly decrease the antenna coupling.
