Abstract:
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.
