Microstrip fed log periodic antenna

摘要

A microstrip fed log periodic antenna has two spaced dipole strips mounted on a ground plane. Each dipole strip has a trunk with a base, tip and alternating arms extending perpendicular to the trunk. One dipole strip includes an integral transmission feed line that extends from the tip, along the trunk of the other dipole strip at constant distance and along the ground plane at a constant distance. The one piece dipole strip with the integral transmission feed line reduces passive intermodulation and simplifies manufacture.
