A Simple Algorithm For the Control of Reactances in Beam Steering Applications With Parasitic Elements

摘要

A crucial part in the design of an ABF system is the calculation of a number of sets of capacitances, which are required to focus the beam in the application-specific directions. Here, optimization schemes are usually employed [4] which are known to become bottlenecks in an accurate and speedy design process. Therefore, this paper presents an analytical algorithm to calculate the capacitances added to the parasitic elements. For given directions, the resulting capacitance sets are always realizable, conform to a specifiable accuracy, and maximize the directed E-field. The procedure is straightforward and completely avoids the use of any optimization routines.
