Dual band antenna

摘要

There is provided an apparatus comprising: a first radiation element having a horizontal pattern extending in parallel with a ground element and having a first open end; a second radiation element having a horizontal pattern extending in parallel with the ground element and having a second open end; wherein each of said first radiation element and second radiation element connects to the ground element; wherein said second open end of the second radiation element occupies an area surrounded by a horizontal pattern of the first radiation element and the ground element; and a driven element including a first excitation pattern extending along the horizontal pattern of the first radiation element and a second excitation pattern extending along the horizontal pattern of the second radiation element. Other embodiments are disclosed.
