Abstract:
1. A log periodic antenna comprising: a ground plane, a one piece first dipole strip having a first trunk with a base, a tip and a plurality of spaced dipole arms extending transverse said first trunk between said base and said tip, said base being mounted on said ground plane, said first dipole strip including an integral transmission feed line that has a first feed line section that extends from said tip of said first trunk, and a second dipole strip having a second trunk with a base, a tip and a plurality of spaced dipole arms extending transverse said second trunk between said base and said tip, said base of said second trunk being mounted on said ground plane and spaced from said first trunk, with said first feed line section bending over and extending, at a selected distance, along said second trunk to near said ground plane, whereby metal to metal junctions between said first trunk and said transmission feed line are eliminated, and passive intermodulation is reduced.
