Abstract

Abstract:

An ultra-wideband microstrip log-periodic antenna (UWB-MLPA) is studied by using genetic algorithms (GA). A multi-object function with low VSWR and high gain is used in the program. The results of GA optimization are compared with traditional methods. An antenna is designed and fabricated, and outdoor measurements carried
out with good results. The antenna can operate in the L/S band with good electrical and radiation characteristics.
It is shown that GA is an effective method for this type of UWB antennas.

Key words: genetic algorithm, ultra-wideband, microstrip log-periodic antenna, multi-object function
