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. A slot extends into the radiating element from one side thereof.
Claims11
A multi-band 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 metal radiating element on said first surface of said substrate;
- said radiating element having a generally right triangle shape including a linear base located generally adjacent to said first edge of said substrate, a first linear side extending from one end of said base, and a second linear side extending from the other end of said linear base, said radiating element having a triangle apex which is formed by the intersection of said first and second linear sides;
- a linear metal feed line including and formed as an extension of said triangle apex, said feed line extending in a direction away from said triangle base and extending from said triangle apex toward said second edge of said substrate;
- a metal ground plane element on said second surface of said substrate, said ground plane element having a first edge located generally adjacent to said second edge of said substrate;
- said ground plane element having a second edge that dimensionally overlaps said feed line and only said apex of said radiating element;
- said ground plane element being electrically connected to said radiating element;
- said radiating element having a slot formed therein which extends inwardly into said first side of said radiating element.
