5G Broadband Radiator, and 5x16 Array Thereof

The phased antenna array is one of the lead front-end components of current and coming 5G communication systems that defines their massive MIMO performance. The trend outlined in recent years is to provide “… a robust and complete platform/wizard for RF/microwave engineers … “ to “… develop … more capable antenna and other RF front-end components in less time as before.” “Benefits of systems operating at mmWave frequencies include the small sizes of antennas and the larger available bandwidth.” Regrettably, a wide variety of application-driven requirements (city or rural environment, a realized gain, scan and polarization performance, impedance matching, etc.) cannot be met by single and forever designed element. Push on image to get to the full text.

Chapter 1 Dimensional Analysis, Vector Differential Operators, and Electrostatic

To boost the flavor of electromagnetics, we accompanied many problems with short Matlab code acting as a calculator and result illustrator. We completely ignored the description of algorithms behind the codes because they are often quite complicated and required ample, very sophisticated as well abstract mathematical specifics poorly helping to understand the physical picture. Such approach let us shift the focus from the often emasculated and practically fruitless problems to more complicated but close to practical tasks. We hope that it helps to visualize typically invisible EM fields and stimulate in-depth analysis and following discussion of the fundamental principles. Projecting images onto a big screen, the lectures may organize whole class conversation making the audience to be more engaged.

Deicing Graphene Nanoribbon Heating Layers

Ice-elimination system is very common in large radio-frequency (RF) structures. They can be classified as either passive antiicing films (preventing the accumulation of ice) or active deicing devices (removing ice after accumulation). Typicallly,  an icing protection system is in radomes. Radomes are protecting shells or covers for radar instruments in aviation and marine environments. The radomes are subject to hostile environments, such as high winds containing sand, rain, hailstones, and saltwater, over wide temperature variations. Explosive pressure blasts can also take place nearby the radomes. Thus, radome deicing conductive films must be extremely tough with good adhesiveness to the heated surface. In addition, these deicing structures must not compromise the reliability of the original RF system, which, in the case of radome applications, means that the deicing film must be predominately transparent to RF radiation at any polarization with minimal impact on the antennas scan performance. It is desirable that this film be lightweight and low-cost, with physical characteristics that allow it to cover large curved surface areas.
