ABSTRACT:
A compact-size planar antenna uses, as a ground plane, a LCD-protective bracket of a portable wireless device with an LCD. The antenna includes a top plate spaced apart from the bracket by a predetermined distance, and a short circuit plate connected to the top plate and the bracket with both ends. A power feed line is connected to the top plate and the bracket with both ends, and a dielectric body having a high dielectric constant is arranged between the bracket and the top plate. The compact-size planar antenna is spaced apart from conductor parts of the portable wireless device by a predetermined distance, and formed at a left lower corner of the portable wireless device when viewed from back of the portable wireless device.
