Abstract : The basic log periodic zig zag antenna is made of one continuous conductor wherein vertical wires function as radiators when they are in resonance. Horizontal wires of the antenna are the phasing stubs, which provide the proper phase shift for the radiating elements. Efficiency of the antenna is enhanced by effectively shortening the path between adjacent elements in the active region with a single conductor. Additionally, a vertical conductor between the shortened path conductor and the respective radiating elements reduces the resonance Q of the vertical radiators and functions as a mechanical support for the radiators.
