Abstract:
1. An antenna for radiating electromagnetic energy comprising: a first dielectric substrate having opposite first and second surfaces; a patch of conducting material disposed on said first surface; a ground plane of conducting material disposed on said second surface; and at least three input means, each input means coupled to a respective one of a plurality of microstrip feed lines, said input means and said microstrip feed lines adapted to electrically couple an input signal to said patch at respective feed points, wherein said feed points are positioned to minimize the total power reflected from each input means, each of said microstrip feed lines having a first end and a second end, said first end oriented away from said patch and said second end oriented towards the center of the patch and said microstrip feed lines tapered such that the width of said microstrip feed lines diminishes along the length of said microstrip feed lines, said width being greater proximate said first end than proximate said second end.
