摘要

研究了一种孔径调谐反f天线的谐波发射。利用天线的传输在线模型进行了解析分析。在分析结果的基础上，给出了高压可切换射频电容对载波聚合前端大信号性能进行优化的实例，并通过硬件验证验证了结果。实验结果表明，通过对电容调谐网络沿主天线辐射单元的位置进行精细选择，可将主分集天线1800 MHz处的二次谐波功率降低10 dB。

Large-Signal Performance Optimization of Inverted-F Antenna Tuned by Switchable RF Capacitor

Harmonics emission by an aperture-tuned IFA (inverted-F antenna) is studied. The analytical analysis is conducted using a transmission-line model of the antenna. Based on the results of analysis, an optimization example for the large-signal performance of a carrier-aggregation front-end tuned by a high-voltage switchable RF capacitor is presented, the findings are supported by the measurements on a hardware demonstrator. According to the experimental results, the power of a second harmonic at 1800 MHz coupled from the main into diversity antenna is reduced by 10 dB by fine-selecting the position of the capacitor-based tuning network along the radiating element of the main antenna.
