Top loaded triangular printed antenna

An antenna comprising:

• a triangular-shaped resonant element, disposed in a first plane, having a top side and two diagonal sides meeting at a bottom;
• a tapered strip section connected at said bottom between said two diagonal sides;
• a microstrip input transmission line connected to said tapered strip section;
• a rectangular strip load connected to the top side of said triangular-shaped resonant element;
• a pair of first arounded strip sections, disposed in said first plane and in parallel to said rectangular strip load, each connected to a grounded surface in a second plane through a plurality of corresponding via holes in said first grounded strip sections and said grounded surface, wherein one grounded strip section located on the left side of said microstrip input transmission line and the other grounded strip section symmetrically located on the right side of said transmission line;
• and
• a second grounded strip section, disposed in a third plane and positioned directly under and in parallel to said first grounded strip sections in said first plane, said second grounded strip section being connected to said grounded surface In said second plane through a plurality of corresponding via holes in said second grounded strip section and arounded surface.
