Printed Wideband Antenna with Chip-Capacitor-Loaded Inductive Strip for LTE/GSM/UMTS WWAN Wireless USB Dongle Applications

In this paper, the authors propose a planar printed 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 LTE 700/GSM850 and 900 (698-960MHz) operation. While the desired upper band is mainly realized by the rectangular radiating patch covering DCS 1800/PCS1900/UMTS2100/LTE2300 and 2500 (1710-2690MHz) band. Easily printed on a 0.8mm thick FR4 di-electric substrate of size 20x70mm2, the proposed antenna structure occupies a compact size of 20x19mm2.
