| 1. An antenna, comprising:
a ground plane having an edge;
a first antenna element extending substantially parallel to the edge;
a ground element that electrically connects the first antenna element with the ground plane;
a second antenna element extending substantially parallel to the first antenna element and disposed between the edge and the
first antenna element,
the second antenna element connected at one end of the second antenna element to the first antenna element and turning back
approximately 180° to extend substantially beside the first antenna element, the remaining end of the second antenna element
being physically separated from the first antenna element and located closer to the ground element than the end of the second
antenna element connected to the first antenna element; and
a third antenna element disposed so that the first antenna element is between the second antenna element and the third antenna
element, the third antenna element at least partially extending substantially parallel to the first antenna element, the third
antenna element having a rear end electrically connected with the first antenna element at an end of the first antenna element
that opposes the end of the first antenna element that is connected to the ground element, the remaining end of the third
antenna element being electrically open.
