ABSTRACT:
An antenna structure has a substrate, having a first-side surface and a second-side surface. A first antenna substructure on the first-side surface has a first straight metal line and a second straight metal line. The second straight metal line joins to the first straight metal line, and is substantially perpendicular to the first straight metal line. A second antenna substructure disposed on the second-side surface has a metal plate, serving as a ground, wherein the first straight metal line is overlapping with the metal plate. An L-shape metal line protrudes from the metal plate, wherein a portion of the L-shape metal line is parallel and overlapping with the second straight metal line, and a portion of the L-shape metal line is parallel to the first straight metal line without overlapping.
