Low-Profile Antenna for Ten Band WWAN/ LTE/WiMAX Smartphone Applications
نویسندگان
چکیده
A small antenna which works in ten bands for slim and wide screen internal smartphone application is proposed here. It consists of a feeding strip, a coupling strip and shorting strip, which can be easily printed on the FR4 substrate. In this scheme three chip inductors and a chip capacitor are loaded on the strips. A parallel resonant circuit is introduced in the design in order to enhance the bandwidth of lower bands. This antenna has a size of 5x40mm and a height of 2mm which is promising for slim and wide screen smartphones. The proposed antenna can operate in GSM850/DCS/ PCS/UMTS2100 /LTE2300/2500/2690, WiMAX-3100/3500, Amateur radio and Bluetooth frequency bands. The design considerations

In this paper, a tunable multiband LTE antenna is designed for metal-rimmed smartphone applications. The antenna only uses a broken metal ring, which comprises an IFA (Inverted-F antenna) section and a parasitic section, and generates three resonant modes through this layout for the feeding point and shorting point. In addition, loading a matching circuit at the feeding point and a RF switch at...
