ABSTRACT:
Multi-band, Inverted-F Antenna with capacitively created resonance, and radio terminal using same. The present invention creates an additional resonance frequency in a planar-style, inverted-F antenna (PIFA), such as that typically used in mobile radiotelephone or other types of radio terminals. A first radiating branch of the antenna is connected to the signal feed conductor and the ground feed conductor. A second radiating branch is connected to the signal feed conductor and the ground feed conductor at one end and is capacitively coupled to the first radiating branch at the other end so that the antenna resonates at an additional resonance frequency. The additional resonance frequency can be used for, among other things, adding GPS or Bluetooth functionality to a radiotelephone terminal that otherwise operates on GSM (Global System for Mobile) or other mobile radiotelephone terminal frequencies.
