Abstract
A communication structure may include a mobile terminal ground plane including a ground point. A primary radiator is electrically coupled to the ground point. A first antenna branch includes a first filter circuit that is coupled between a first point on the primary radiator and a first antenna port and that corresponds to a first frequency band. A second antenna branch includes a second filter circuit that is coupled between a second point on the primary radiator and a second antenna port 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.
