    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.
