TWO PORT ANTENNAS WITH SEPARATE ANTENNA BRANCHES INCLUDING RESPECTIVE FILTERS

摘要

A communication structure may include a mobile terminal ground plane including a ground point (119). A primary radiator (205) is electrically coupled to the ground point. A first antenna branch includes a first filter circuit (212) that is coupled between a first point (216) on the primary radiator and a first antenna port (214) and that corresponds to a first frequency band. A second antenna branch (220) includes a second filter circuit (222) that is coupled between a second point (226) on the primary radiator and a second antenna port (224) that corresponds to a second frequency band that is different from the first frequency band. In addition, a radio frequency (RF) transmitter and/or receiver may be provided with the ground plane and the primary radiator being electrically coupled to the RF transmitter and/or receiver.
