Printed Monopole Antenna With a Long Parasitic Strip for Wireless USB Dongle LTE/GSM/UMTS Operation

In this letter, a new planar printed ultrawideband antenna for wireless USB dongle eight-band 698-960 and 1710-2690 MHz has been proposed based on the simulation and experimental studies. The presented antenna, occupying a compact size of 19×20 mm
²
, embodies a rectangular patch and a long parasitic strip, which are directly printed on the top of the employed FR4 substrate. Nearly 115% VSWR <; 3 impedance matching bandwidth and over 54% radiation efficiency with 1.8 dBi antenna gain is obtained from the measured results.
