Abstract

A method for an antenna architecture for handling various Digital Video Broadcast (DVB) channels may be provided. The method may comprise receiving, at a first circuit, a first signal within a 850 MHz band, a 1900 MHz band and/or a 2100 MHz band, wherein the first circuit is integrated within the mobile terminal and is operably coupled to a first antenna and/or a second antenna. Second signals within the 850 MHz band, the 1900 MHz band and/or the 2100 MHz band may be received at a second circuit, wherein the second circuit is integrated within the mobile terminal and is operably coupled to the first antenna. A video broadcast signal may be received at a third circuit, wherein the third circuit is integrated within the mobile terminal and is operably coupled to a third antenna.
