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 کاملReview Paper On Ultra Wideband Log-Periodic Antenna For Wireless Communication
Log-periodic array antennas have been investigated over a long period of time, the reason for the same being its provision of a constant radiation performance and good reflection coefficient performance over a wide frequency band, which can be considered as an important characteristic of this type of antennas. It created a high impact on development of new generation antennas with advanced feat...
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 کاملA Compact Printed Dipole Antenna for Wideband Wireless Applications
A compact printed dipole antenna with wide impedance bandwidth is proposed in this paper. This antenna consists of a pair of radiation metal arms and a microstrip-to-slotline transition structure. At the end of the feeding slotted line, a beveled slot with stepped connection structure is designed to realize an offset feeding structure for feeding the dipole antenna. By using the beveled offset ...
متن کاملSpade-Shaped Patch Antenna for Ultra Wideband Wireless Communication Systems
In recent years many studies are concentrated on UWB microstrip antenna structures for important purposes in wireless communication systems, medical imaging, and radar sensor resolution. In this paper, we printed a spade-shaped radiator patch on nearly rectangular substrate of (30 x 28mm) made of Taconic TLY-5 material. The relative dielectric constant was 2.2, and the thickness of the material...
