Software Development and Construction of Log Periodic Dipole Antenna Using MATLAB

Abstract: Technological advantages in solar activities particularly in solar radio burst (type I, II, III, IV, V) in radio region have created a demand of designing and constructing of Log Periodic Dipole Antenna (LPDA) to monitor. LPDA also plays an important role in modern communication systems such as TV, radar etc. The lengths and spacing of the elements of a LPDA are increases logarithmically from one end to the other. This paper presents the types of LPDA, mathematical equations required to design, flow-chart, MATLAB (MATRIX LABORATORY) code to obtain the antenna parameters and structure dimensions of the antenna elements to construct and the details of constructed LPDA of frequency range of 160MHz to 1900MHz with 24 elements. MATLAB tools and built-in math functions enables to explore multiple approaches and reach a solution faster than traditional programming languages, such as C/C++ or Java. It provides a good accuracy to calculate LPDA structure parameters required for LPDA design.
