INVERTED F ANTENNA CAPABLE OF EASILY CONTROLLING BANDWIDTH AND GAIN

摘要

PURPOSE: An inverted F antenna in which parasitic coupling resonance is added is provided to enhance radiator availability by forming a resonance part which is closely arranged with a grounding wire and a signal wire in order to couple.;CONSTITUTION: A resonance part(130) is closely arranged with a grounding wire and a signal wire in order to couple. One side of the resonance part is connected to a radiator of an inverted F antenna. The other side of the resonance part is connected to the grounding wire. The resonance part comprises one or more elements and controls bandwidth of the inverted F antenna. The element offers inductance and capacitance. The resonance part improves bandwidth and gain of one among one or more frequency band. One or more matching elements interlink the resonance part and the inverted F antenna.;COPYRIGHT KIPO 2012
