【摘要】 针对未来移动通信,提出了一种新颖的采用可调电感和电容TIC（Tunable Inductor and Capacitor）方法的可调谐双频平面倒F天线PIFA（Planar Inverted-F Antenna）。两个可调电容（C₁和C₂）和一个可调电感（L）的调谐范围分别为0.1 pF～2.0 pF、12.0 pF～20.0 pF、4.6 nH～15.8 nH。HFSS仿真结果表明,在回波损耗大于14 dB条件下,采用TIC方法的单根可调谐双频PIFA天线的两个频率范围分别为700 MHz～970 MHz和1 690 MHz～2 710 MHz,可以完全覆盖中国2G/3G/4G频谱。本研究为进一步减小天线尺寸提供有效方法,可在5G移动通信中得到重要应用。更多还原

【Abstract】 A novel tunable dual-band planar inverted-F antenna（ PIFA） with tunable inductor and capacitor（ TIC） is proposed for future mobile communication. The tuning ranges of two tunable capacitors（ C₁ and C₂） and one tunable inductor（ L） are 0. 1 p F ～ 2. 0 pF,12. 0 p F ～ 20. 0 p F,and 4. 6 n H ～ 15. 8 n H respectively. HFSS simulation result shows that two frequency ranges of a single tunable dual-band PIFA with TIC are 700 MHz ～ 970 MHz and 1 690 MHz ～ 2 710 MHz at | S₁₁| >14 d B. The frequency bands of the tunable dual-band PIFA with TIC can fully cover2 G/3 G/4 G spectrum in China. This study provides an effective method for further reducing antenna size,and can be used in 5 G mobile communication.更多还原
