Design of an internal planar monopole antenna for WUSB dongle application

In this paper, an internal planar monopole antenna for use in WUSB dongle application is proposed. The antenna, suitable for WUSB dongle application, occupies a compact area of 20 mm × 10 mm × 1 mm. The planar antenna consists of a modified meander-strip and an inverted L-strip. The antenna elements are printed on the top and bottom sides of substrate, respectively. The impedance bandwidth of proposed antenna is enhanced by the mutual coupling between the modified meander-strip and inverted L-shape strip.
