A new look in antenna structures results from the application of the log periodic concept in antenna design. This new family of antennas exhibits pattern and impedance characteristics which are essentially frequency independent over extremely wide bandwidths. Ten-to-one bandwidths are readily attained in practice. Various configurations can provide vertical or horizontal linear polarization as well as circular polarization. Radiation patterns can be made uni-, bi-, or omnidirectional with relative ease. This paper shows how to design practical antennas for amateur use at low cost and includes several practical sets of working construction dimensions.
