Abstract
In this paper, the broadband antenna design, which can be applied to USB Dongle, supporting Wibro(2.3~2.4 GHz), Wi-Fi(2.4~2.5 GHz) and LTE7(2.5~2.7 GHz) is proposed technique. The proposed antenna was designed similar to PIFA type antennas. Reactive elements were used to control the input impedance and wideband characteristics were achieved by controlling coupling between the feed structure and the radiator. As a result, the antenna printed on FR-4 PCB(${\epsilon}_r$ =4.4, tan ${\delta}$=0.02) occupying an area of $15{\times}5mm^2$ was able to achieve bandwidth of 1 GHz from 2.1 to 3.1 GHz under VSWR=2. Measured return loss characteristics, bandwidth and radiation patterns were in good agreement with the simulated results.
