Abstract: This paper attempts to overcome the limitations of the parametric curves that characterize
the performance of the Log Periodic Dipole Array Antenna (here after referred to as the LPDA). For
instance, the parametric curves in design handbooks e.g. ARRL antenna handbook and other relevant
literature e.g. Peixeiro do not contain those giving the relationship between the boom-length 'L' and
the number of dipole element 'N' for any given bandwidth, even when it is known that these two
parameters are the main cost determinants of a LPDA Antenna. The concept of convergence is
introduced to aid cost optimization of the LPDA Antenna in terms of number of dipole element 'N'.
Although 'N' is used as the minimization criterion, the criteria for establishing convergence
encompass all the main electrical characteristics of the LPDA antenna, such as VSWR, gain and
radiation patterns.
