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...
متن کاملDesign of a Printed Log-periodic Dipole Array for Ultra-wideband Applications
Abstract—A printed Log-periodic dipole array (LPDA) is presented, operating over the C, X and Ku bands. The antenna feeding structure consists of two coaxial cables, in order to realize an infinite balun which provides the required broadband input matching. The second coaxial cable mirrors the first one, connected to the antenna input, and is capable of both stabilizing the antenna phase center...
متن کاملPhD Thesis: Wideband Wireless Full-Duplex transceivers for 5G communications
In recent years, the concept of full-duplex (FD) communications has been the subject of a large attention from the scientific community. Recent advances in both analog and digital parts of radio transceivers offer now the possibility to consider the use of the full-duplex approach for operational systems. Unfortunately, current developments are mainly focused on narrowband systems. The heart of...

متن کاملCircularly Polarized Log-Periodic Dipole Antenna for EMI Measurements
Two types of broad-band antennas are widely used for electromagnetic interference (EMI) measurements in the frequency range from 30 to 1000 MHz. Log-periodic dipole antennas (LPDA) are mainly used for the range above 300 MHz and biconical antennas for the range less than 300 MHz. These two antennas have linear polarization. However, EMI measurements can sometimes be more conveniently made with ...
