A New Design of Log-Periodic Dipole Array (LPDA) Antenna

This paper presents a new approach for design of the log-periodic dipole array antenna (LPDA) based on using of different design parameters in the LPDA elements to control the antenna behavior. In the proposed procedure, the design parameters can control the value of forward gain over the operating frequency range, and also adjust the gain flatness. Furthermore, this design procedure can decrea...

an infinite planar array of rectangular microstrip patch antenna analysis

the methods which are used to analyze microstrip antennas, are divited into three categories: empirical methods, semi-empirical methods and full-wave analysis. empirical and semi-empirical methods are generally based on some fundamental simplifying assumptions about quality of surface current distribution and substrate thickness. thses simplificatioms cause low accuracy in field evaluation. ful...

Design Optimization of Log Periodic Dipole Antenna Using Genetic Algorithm

In this paper,design optimization of Log Periodic Dipole Antenna (LPDA) has been carried out using Genetic Algorithm. The design objectives of this work is maximization of gain and minimization of VSWR.This has been achieved by variations in geometrical parameters of log periodic dipole antenna like maximum length, minimum length,spacing factor (σ). The simulation results have attained gain fro...

A Printed Log-periodic Tree-dipole Antenna (plptda)

Abstract—A miniaturized printed log-periodic fractal dipole antenna is proposed. Tree fractal structure is introduced in an antenna design and evolves the traditional Euclidean log-periodic dipole array into the log-periodic second-iteration tree-dipole array (LPT2DA) for the first time. Main parameters and characteristics of the proposed antenna are discussed. A fabricated proof-of-concept pro...
