Abstract
A compact planar antenna is disclosed wherein a radiating element in the shape of a right triangle is formed on a substrate. A ground plane may be positioned on one or both sides of the substrate. In one embodiment, the radiating elements are positioned on the substrate in groups of two or more in close proximity to one another. In another embodiment, the radiating elements are arranged in an array.
Claims9
A compact planar antenna, comprising:
- a flat dielectric substrate having a first surface, a second surface that is generally parallel to said first surface, a first edge, and a second edge which is located generally opposite said first edge;
- a generally right-triangle-shaped metal radiating element on said first surface, said radiating element having an apex which is formed by the intersection of two linear triangle sides, and said radiating element having a linear triangle base at whose opposite ends said triangular sides terminate, said triangle base being located generally adjacent to said first edge;
- a linear metal feed line including and formed as an extension of said apex;
- a first metal ground plane embodiment on said second surface, said first ground plane element having a first edge located generally adjacent to said second edge of said substrate;
- and
- said first ground plane element having a second edge that dimensionally overlaps said feed line and only said apex of said radiating element.
