This book presents the research of planar printed antennas for WLAN and UWB communication systems. At firsta 2.4-GHz horizontally polarized omnidirectional planar printed antenna adopts the printed Alford-loop-type structure for WLAN applications is presented. The study of the antenna printed on a simulated PCMCIA card and that inserted inside a laptop PC are also conducted. Secondly, a planar triangular monopole antenna (PTMA) is presented for UWB communication. The measured voltage standing wave ratio is less than 3 from 4 to 10 GHz. Then, a novel technique to enhance the bandwidth of the conventional PTMA is presented. With two symmetrical corrugations extended from the flat ground plane, a significant improvement on the impedance bandwidth up to about 4:1 can be achieved. Measured VSWR of the printed PTMA with the ridged ground plane is less than 2 from 3 to 12 GHz. The measured antenna patterns also show the monopole-type omni-directional radiation patterns from 3 to about 10 GHz.
