Design and Analysis of Printed Planar Flat-Plate Dual-Band Wlan Antenna

In this paper, dual-band WLAN service, a low-cost single-sided antenna design is proposed. A 50 mini-coax cable is employed for the connection to the dipole antenna, which is rectangular in shape and measures 10 mm by 37 mm. Each radiating arm may be made into two dipole arms by cutting two L-shaped holes through each. The two resulting dipole arms are then merged to operate in the 2.4 and 5 GHz bands, respectively. Short dipole arms enable the antenna to be created by pressing a flat metal plate. A excellent omnidirectional radiation pattern is seen and the impedance bandwidth for 2.4/5 GHz WLAN operation is at VSWR less than 1.5.
