Abstract
An antenna transducer, and an associated method, for a mobile station operable in a cellular communication system. The mobile station also includes GPS receive circuitry for receiving and operating upon GPS (global positioning system) signals. The antenna transducer includes a primary antenna transducer portion for transducing signals generated to effectuate a communication service in the cellular communication system. And, the antenna transducer includes a second antenna transducer portion for transducing GPS signals transmitted to the mobile station. The primary and second antenna transducer portions are disposed upon a common substrate, and the second antenna transducer portion exhibits circular polarization characteristics.
Claims18
In a radio device for operating upon first radio signals communicated within a first frequency bandwidth and second radio signals communicated within a second frequency bandwidth, an improvement of an antenna transducer formed upon a substrate having a face surface, a first side surface, and a second side surface, said antenna transducer comprising:
- a primary antenna transducer portion disposed at the substrate and comprising a first transmission line formed at the face surface of the substrate, said primary antenna transducer portion for transducing the first radio signals, said primary antenna transducer portion having a first primary antenna transducer part and a second primary antenna transducer part;
- and
- a second antenna transducer portion also disposed at the substrate and comprising a second transmission line formed at the first side surface and at the second side surface of the substrate, said second antenna transducer portion for transducing the second radio signals, said second antenna transducer portion positioned relative to the first and second primary antenna transducer parts, respectively, such that energy transduced by said primary antenna transducer portion facilitates operation of said second antenna transducer portion.
In a method for communicating at a radio device that operates upon first radio signals communicated within a first frequency bandwidth and second ho signals communicated within a second frequency bandwidth, an improvement of a method selectably transducing the first and second radio signals, respectively, said method comprising:
- selectably transducing the first radio signals at a primary antenna transducer portion posed at a substrate and comprising a first transmission line formed at a face surface of the substrate;
- and
- selectably transducing the second radio signals at a second antenna transducer portion disposed at the substrate and comprising a second transmission line formed at a first side face and at a second side surface of the substrate, the first and second antenna transducers at which the first and second radio signals are transduced, respectively, positioned relative to one another such that energy selectably transduced by the primary antenna transducer is at frequencies outside of the second frequency bandwidth.
