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.
