a planner inverted F antenna apparatus of a wireless communication device and a PDA using this antenna

The small planar antenna and a PDA using the same in a wireless communication device is disclosed. Small planar antenna of the present invention, LCD protective bracket; A top plate that are spaced apart from the bracket and the predetermined distance; It characterized in that it comprises; short-circuit strips are attached to both ends of the top plate and the bracket. In addition, the small planar antenna according to the present invention preferably further comprises a high dielectric constant is arranged between the further comprising a feed line that is attached at both ends to said top plate and said bracket, said bracket and the top plate dielectric. Further, PDA of the present invention using the small-sized flat antenna, LCD and as a PDA including a bracket for protecting the LCD, is attached at both ends to said bracket and the predetermined distance the top plate, the top plate and the brackets that are spaced apart which includes a short circuit strip, it characterized in that it comprises a small planar antenna device having the bracket with the ground plane. The small planar antenna is preferably mounted at a remote location from other conductive components on the PDA, in particular it provided on the lower left corner of the rear when seen from the PDA.
