A 2.4GHz omni-directional horizontally polarized planar printed antenna for WLAN applications

This paper presents the design simulation, implement, and measurement of a 2.4 GHz omni-directional horizontally polarized planar printed antenna for WLAN applications. The HFSS 3D EM simulator is used for design simulation. The antenna is fabricated on a double-sided FR-4 printed circuit board. The antenna pattern measurements are performed for the antenna alone in free space, printed on a PCMCIA card, and inserted inside a notebook PC. In addition to being used alone for a horizontally polarized antenna, it can also be a part of a diversity antenna.
