Wire-Grid and Sparse MoM Antennas: Past Evolution, Present Implementation, and Future Possibilities

Since the end of 19th century, radioelectronic devices (REDs) have actively penetrated into all modern community spheres. Achievements in fields radio engineering and electronics, as well computing, information, telecommunications, other technologies, greatly contributed to this. The main elements REDs are antennas microwave devices. For example, linear (wire) basis long-distance communication agency networks various law enforcement agencies departments. manufacturing requires regular rapid appearance more advanced types with minimal costs. At same time, design complexity tightening EMC requirements caused by growth upper frequencies useful interfering signals, mounting density, capabilities generators intentional electromagnetic impacts, together need take account inter-element, inter-unit, inter-system interference, require accurate designs REDs. However, this becomes impossible without computer modeling, which saves time financial resources required for their development, evaluate correctness proposed technical solutions. During process, a rule, multivariate analysis or optimization product is performed. In case, methods computational electrodynamics (one method moments) used. They based on replacement continuous functions discrete analogues (construction grid), reduces problem solution system algebraic equations (SLAE). problem’s depends SLAE solution, determined its order (which turn simulated object surrounding area) number solutions each (determined frequency signal, number, range optimized parameters). This dramatically increases cost, constraint optimal design. Therefore, reducing cost RED (in particular, antennas) an important scientific problem. Meanwhile, finding new antenna structures that meet desired features (low price, characteristics, manufacturable small dimensions windage, etc.) no less today. One promise these problems using wire grid sparse modeling constructing antennas. last lot research has been performed them. aim paper review history related aspects such computational, acceleration, used methods, application, evolution moment. addition, provides possible future implementation wire-grid from authors’ point view presenting under obtain effective
