| Summary: | First results of the development of a tunable antenna for cellular phones operating in the standard LTE are presented. The antenna consists of high- and low-frequency branches, the latter one is tuned by digital-controlled capacitor. Computer simulation of the antenna was conducted by using the RFS. Simulation results show that low-frequency antenna branch can be tuned without detuning high-frequency one. Radiation efficiency of the antenna in high-frequency band yields 60 % or more, while in low-frequency range efficiency drops to 20…30 %. The work on improving these results is now continuing. |
