1. An antenna comprising:

  • a substantially straight main member, wherein the main member is metal and is embedded in a substrate, the main member generally perpendicular to a plane of the substrate and passing through a portion of the substrate;

    a first lateral member, a central part of which is electrically coupled to an upper end of the main member such that the main member and the first lateral member generally form a T shape, the first lateral member having a generally rectangular shape when viewed from above the T shape;

    a second lateral member, a central part of which is electrically coupled to the main member, wherein the second lateral member is spaced from and parallel to the first lateral member, and the second lateral member is embedded in the substrate; and

    a turning circuit coupled to the antenna for varying resonance of the antenna, wherein the first lateral member and the turning circuit are located on a same layer of the substrate.
