Abstract

This paper proposes a planar printed ultra-wideband antenna for eight-band LTE/GSM/UMTS WWAN wireless USB dongle applications. An inductive shorted strip with a chip capacitor loaded is employed in order to improve the characteristics of small-size terminal antennas which usually have a narrow band over the LTE700/GSM850/900 (698-960 MHz) and DCS1800/PCS1900 /UMTS2100/LTE2300/2500 (1710-2690 MHz) operation. Easily printed on a 0.8-mm thick FR4 dielectric substrate of size 20×70 mm², the proposed antenna structure occupies a compact size of 20×19 mm². Then the proposed design can be attached to laptop computer by the USB interface. The proposed antenna is fabricated and tested, and good radiation performances of the fabricated antenna are obtained.
