ABSTRACT:
A microstrip slot dipole antenna of the inverted F type, includes a coplanar feed, and is suitable for easy peel-and-stick adhesive mounting. The antenna includes a ground plane, a dielectric layer, a horizontal element and a pair of spaced apart vertical elements depending therefrom defining an inverted F antenna above the ground plane with the dielectric layer therebetween. The pair of vertical elements may be conductive vias. A first antenna feed point is on an upper surface of the horizontal element, and a second antenna feed point is on an upper surface of a second vertical element of the spaced apart vertical elements. The second feed point may be a conductive pad on the dielectric layer spaced apart from a first vertical element and insulated from the horizontal element.
