Abstract :
In the letter, a simply printed planar antenna covering GSM850/900/1800/1900/UMTS2100 and LTE700/2300/2500 operating frequency bands for wireless USB dongle applications is proposed, designed, and fabricated. The presented antenna consists of a large patch and a matching network in order to enhance impedance bandwidth. The upper operating bands including GSM1800/1900/UMTS2100/LTE2300/2500 are primarily attributed to the large patch. Meanwhile, the lower resonant modes covering LTE700/GSM850/900 bands are generated physically by ground planes of both the USB dongle circuit board and the laptop board. The impedance matching over all bands is improved by the matching network. The proposed antenna occupies a small size of 20 ×20 mm2 and can be easily printed on a 0.8-mm-thick FR4 substrate of conventional dimensions of 20 ×70 mm2, which makes it promising for wireless USB dongle applications.
