IMPROVED CELLULAR ANTENNA ARCHITECTURE
First Claim
1. A mobile unit for use in a wireless communication system comprising:
- a first antenna capable of operating at a first frequency and a second frequency;
a second antenna capable of operating at a third frequency and a fourth frequency; and
a control circuit for unifying the first antenna and second antenna comprising a phase shift circuit for preventing the first antenna from operating at the third frequency and the fourth frequency, and for preventing the second antenna form operating at the first frequency and the second frequency.

Abstract
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.
