Abstract in another language
A penta-band inverted-F antenna (IFA) tuned by two high-voltage aperture tuning networks is presented in the paper. The design is based on a singe, non-bended radiating arm IFA. Each of the two aperture tuners comprises a high-voltage switchable RF capacitor IC in parallel with an off-chip inductor. The antenna can be tuned to any of the 5 bands of sub-4 GHz cellular spectrum between 690 MHz and 3800 MHz with return loss exceeding 6 dB at the feed over more that 95% of the total frequency range. A systematic design and analysis of the penta-band IFA based on transmission line model is provided, tuning approach for carrier aggregation enablement over two bands at a time is discussed. A nonlinear performance of the designed antenna with RF capacitors fabricated in bulk-CMOS RF-switch technology is demonstrated.
