My Personal Antenna Modeling SoftwareThe following program, is a MathCAD (r) file for designing and analyzing a Log-Periodic Dipole Array made with flat elements. No documentation is provided, but the algorithm closely follows that of the Round LPDA program below.
The following program is an executable file for analyzing LPDA's made of tubular elements. It can also be found in Dr. Constantin Balanis' Antenna Theory, Analysis and Design.
Documentation for the round LPDA design program. -- Round LPDA's (Documentation)
Source Code for the round LPDA design program. -- Round LPDA's (Source Code)
Revision History for the round LPDA design program. -- Round LPDA's (Revision History)
