ANTENNA STRUCTURE

摘要

An antenna structure is disclosed. The antenna structure includes a symmetrizing portion and two radiation portions. The symmetrizing portion has an axis and two radiation portions are symmetrically connected to the symmetrizing portion along the axis. Each of the two radiation portions is formed in a boot shape within a quadrilateral region having a first edge with a first length, a second edge with a second length, a third edge with a third length and a fourth edge with a fourth length. Each radiation portion includes a first side having a length being equivalent to the first length, a second side having a length being equivalent to the second length, a third side having a length being at least one-sixth of the third length, a fourth side having a length being at least one-fifth of the fourth length, and a fifth side connecting the third side and the fourth side and forming an arc, wherein the arc follows a quarter trajectory of an ellipse.
