Abstract
A cellular phone and method for receiving and transmitting signals of different frequency bands and wireless standards utilizes an architecture that allows the use of switches that are less expensive and less lossy than switches used in comparable cellular phones. The architecture also allows the use of only narrow-banded antennas, rather than a combination of a narrow-banded antenna and a harmonic antenna. As a result, the performance of the cellular phone can be significantly improved.
