摘要： An antenna architecture permitting tri-band and quad-band transmission and reception of GSM standardized frequencies in a mobile unit with a required gain without increasing power consumption. The mobile unit utilizes a control circuit to unify a first antenna and a second antenna, wherein the first antenna can operate in a first frequency and a second frequency and the second antenna can operate in a third frequency and a forth frequency. The control circuit includes a phase shift circuit for each antenna. The phase shift circuits prevent each antenna from loading the other antenna effectively eliminating excessive VSWR to increase gain.

摘要： An antenna module includes an antenna, a tunable matching circuit, a power detector and a control unit. The antenna comprises a feeding point. The tunable matching circuit, electrically connected between the antenna and the power detector and configured to provide a loading impedance, comprises a plurality of tunable impedance elements connected to each other and electrically connected to the feeding point as well. The power detector is electrically connected between the tunable matching circuit and a power amplifier and configured to detect a power indicator. The control unit, electrically connected to the tunable matching circuit and the power detector, is configured to read the power indicator and RSSI to generate a control signal for the tunable matching circuit, which consistently changes the loading impedance to achieve impedance matching.
