| Abstract: | A broadband dual frequency sleeve monopole antenna for application in digital television (DTV) systems and global system for mobile communications (GSM) is presented. A parasitic inverted L-shaped strip and dual planar sleeve structure are introduced in the back ground plane for expanding the frequency band. The simulated and measured results show that the impedance bandwidth covers the DTV (470? 862 MHz) band and GSM (824?960 and 1710?2170 MHz) band with VSWR less than 2.5. An omnidirectional radiation property is also shown. |
