摘要

本文介绍了一种具有可调谐射频电路和自动S11计算算法的手机闭环广域网天线系统,该系统可以动态优化天线回波损耗,以减少头部和手部用户对天线阻抗匹配的影响。对天线S11的测量表明,在900频段,即使失谐超过150 MHz,天线谐振也能移回原频率。

A closed loop WAN antenna to reduce head and hand effects for mobile phone applications
In this paper, we introduced a mobile phone closed loop WAN antenna system with tunable RF circuits and automatic S11 calculation algorithm that can dynamically optimize antenna return loss to reduce the head and hand user effects on the antenna impedance matching. Measured antenna S11 indicates that antenna resonance can shift back to original frequency even it is detuned for over 150 MHz at 900 band.
