As wireless communication systems are developing at a rapid pace, traditional antennas with fixed functionalities pose to be a limitation. Thus, reconfigurable antennas play a major role by incorporating multifunctional capabilities into a single antenna system. This paper reviews different types of antenna reconfigurations such as frequency, pattern, polarization and compound reconfigurable antennas. The design techniques employed to achieve reconfigurability along with its applications is...

A product catalog from EMCEE Broadcast Products, a division of Electronics, Missiles & Communications, INC. The title of the catalog is Low Power Television Stations for VHF, UHF, and S-Band and it details transmitters, translators, and antennas. It is potentially missing pages, it looked quite ripped, and I found two loose pages which seemed to be from the catalog, but were not found physically within the catalog itself and instead were found in a different pile of papers.

A book detailing theory and design of various types of antennas. The book is composed of three parts. The first part deals with general theory of radio wave propagation, radiation and reception. Using classical electrodynamics different antenna types are described with their parameters. Second part describes theory of transmission lines of radio waves. Different configurations of transmission lines and their effects are derived. The third part of the book describes different types of antenna...

This is an antenna mount for a 3/8x24 vertical stud mount antenna. It attaches using standard fender bolts & washers onto the pre-drilled box link holes on a pickup truck. The measurements were derived from the 2018 - 2021 F-150 models, but it should fit other makes & models as well, so long as the truck has been drilled for box link anchors. This will fit in place of a boxlink tiedown anchor. It will not fit over the top of one. It's recommended to use PETG, ABS or some other similar...

This book gives a comprehensive presentation of reflectarray antennas. It is well organized and has significant amount of information in design and analysis with many practical application results augmented with adequate number of references to help the readers to comprehend. Undoubtedly, this book is not only well suited as a university text book but also is an excellent source of design and analysis information for antenna engineers for many years to come.
Topics: Electronics, antennas, parabolic, reflector, array

Fundamentals of Microwave and RF Design enables mastery of the essential concepts required to cross the barriers to a successful career in microwave and RF design. Extensive treatment of scattering parameters, that naturally describe power flow, and of Smith-chart-based design procedures prepare the student for success. The emphasis is on design at the module level and on covering the whole range of microwave functions available. The orientation is towards using microstrip transmission line...

The book is a monograph written as a result of research by the author. The diffraction of plane electromagnetic waves by ideally conducting bodies, the surface of which have discontinuities, is investigated in the book. The linear dimensions of the bodies are assumed to be large in comparison with the wavelength. The method developed in the book takes into account the perturbation of the field in the vicinity of the surface discontinuity and allows one to substantially refine the approximations...

In this paper, multiple-input and multiple-output (MIMO) antennas are designed and simulated. The designed antennas are compact double-sided printed microstrip patch antennas and fed by a microstrip line. These antennas are designed for 3.5 to 10 GHz frequencies used for medical, industrial, sciences, and various fields of 5G communications and networking applications. Furthermore, a MIMO system is designed using the polarization variability of the individual antennas, which yields better...

This study proposes a system consisting of a “patch”[1] dual-band antenna [2] with slots, dimensioned for 5G applications. In this device an AMC ("Artificial Magnetic Conductor") structure was inserted in order to improve the operating characteristics. The AMC plane [3] is formed using a 2 x 2 matrix of unit cells, each with a U-shape and a reconfigurable element. The results compared with an antenna without AMC indicate that the system provides SAR reduction, directivity...

Before Facebook, Twitter, YouTube, and even the Internet, there was Public Access Cable. Return with us now to Columbus, Ohio in the 1990s for the journal of pop culture. Don’t worry—it’s not the final episode of this series, but a review of famous finales. (Of course, if my tape player gives up the ghost, the end will be closer than planned).
