Electromagnetically Coupled Inverted-FL Antenna with Self-Complementary Structure for Mobile Phone
Nobuyasu Takemura,Young Eil Kim 대한전자공학회 2009 ITC-CSCC :International Technical Conference on Ci Vol.2009 No.7
In this paper, the authors describe the inverted-FL antenna design. This unique design is realized by integrating the electromagnetically coupled inverted-F antenna with a self-complementary structure with an inverted-L element. The proposed antenna realizes a broadband characteristic without matching load and impedance transformer to match 50 ohms using electromagnetically coupled feeding structure. This antenna acquired the broadband and multi-band characteristics covering the GSM850/GSM900/DCS/PCS/UMTS2100/UMTS2600 bands and the 2.5G/3.5G bands for Mobile WiMAX by simulation and measurement.
