Abstract
A portable terminal includes a small-sized built-in antenna apparatus having an excellent electric performance. The built-in antenna apparatus includes a ground plate and an antenna unit. The ground plate includes a feed point. The antenna unit is disposed adjacent to an end of the ground plate. The antenna unit includes a reverse L-shaped antenna element. One end of the L-shaped antenna element is connected to the feed point and an opposite end of the L-shaped antenna has a helical shape. A magnetic piece is loaded at a portion where current distribution of the L-shaped antenna element is high, and a dielectric piece is loaded at a portion where current distribution of the L-shaped antenna element is low.
