Abstract
Technologies directed to a slot antenna as a calibration antenna for a phased array antenna are described. The antenna structure includes a ground plane, a first antenna element, and a second antenna element. The first antenna element and the second antenna element are located in a first plane that is separated from the ground plane by a first distance. The second antenna element is separated from the first antenna element by a second distance. Conductive material is located in the first plane the first antenna element and the second antenna element. A portion of the conductive material adjacent to the first antenna element includes a slot antenna. A radio frequency feed point is located at the slot antenna. The conductive material electrically isolates the first antenna element and the second antenna element and radiates electromagnetic energy as a slot antenna.
