Abstract
In this paper, multiband printed dipole antennas using parasitic elements are proposed for multiple wireless services. First, an elementary dipole antenna is studied and characterized at the operating frequency of 2.9 GHz. Next, two compact dual-band planar-antenna configurations are presented. The first antenna is suitable for nautical RADAR detection in both the L- and X-bands, whereas the second is suitable for Bluetooth and WiFi or WiMax applications. Finally, a triple-band printed dipole antenna with two parasitic elements is designed to operate at triple-band for IMT-2000, 5-GHz WLAN, and X-band ISM, respectively. Prototypes of the proposed antennas are constructed and tested. All the antennas have a simple geometry and can be easily fed using a 50Ω coaxial probe or directly integrated in the PC board with a microstrip line. Details of the experimental and simulation results are presented and discussed. © 2006 Wiley Periodicals, Inc.
