Dual-band Inverted-F Antenna with Tunable Inductor and Capacitor for 5G Mobile Communication

A novel dual-band inverted-F antenna (IFA) with tunable inductor and capacitor (TIC) for 5G mobile communication is proposed. The tuning ranges of two tunable capacitors (C 1 and C 2 ) and one tunable inductor (L) are 0.1-1.0 pF, 1.3-4.8 pF, and 2-6 nH respectively. Simulation results of the dual-band IFA with TIC are obtained by using HFSS. It shows that two frequency ranges of the dual-band IFA with TIC are 2.74-3.74 GHz and 4.44-5.0 GHz at the return loss better than -15 dB. The frequency of the dual-band IFA with TIC can fully cover the 5G spectrum in China.
