Innovative Tunable Antenna Solution Using CMOS SOI Technology
Résumé
This paper describes a tunable matching network, fully integrated in STMicroelectronics 130 nm CMOS SOI technology. It is able to correct, on the 2500-2690 MHz band, the antenna mismatch of a cellular phone due to the user interaction (for example the hand impact):any VSWR of 5:1 can be reduced to a value lower than 2:1.
