Abstract :
In this paper, the concept of reduced ground-plane effect is proposed in the design of small ultra-wideband (UWB) antennas for portable devices. The antenna is designed with a notch cut from the radiator, which concentrates most of the electric currents on the upper radiator at lower operating frequencies. A short strip is used to further reduce the size of the notched antenna. Next, the design is applied to a laptop computer. The antenna designed for wireless universal serial bus (W-USB) dongle installed on a laptop computer shows the advantage of a significant suppression of lossy object/ground-plane effects on the impedance and radiation characteristics of the antenna
