ABSTRACT:
The planar antenna apparatus may include a planar, electrically conductive, patch antenna element having a geometric shape defining an outer perimeter, and a pair of spaced apart signal feedpoints along the outer perimeter of the planar, electrically conductive, patch antenna element and separated by a distance of one quarter of the outer perimeter to impart a traveling wave current distribution. The outer perimeter of the planar, electrically conductive, patch antenna element may be equal to about one operating wavelength thereof. The apparatus may provide dual circular or dual linear polarization. The planar patch element may relate to a full wave loop antenna as a compliment.
