Über dieses Buch

This book provides solutions to a complex of internal and external problems of electromagnetics associated with the development of theory, construction of mathematical models and the development of rigorous methods for calculating the electrodynamic characteristics of radiating structures and antenna arrays with impedance vibrator and slot elements. The issues related to the impedance synthesis of antenna arrays and analysis of large-aperture rectenna arrays are considered. Solutions to the problems of determining the electrodynamic characteristics of impedance vibrators, slot and multi-element radiators with arbitrary geometric and electrophysical parameters are obtained within the framework of a unified methodological approach to constructing asymptotic solutions of integral equations for currents. This approach made it possible to study a number of new vibrator, slotted, and combined vibrator-slotted structures and their multi-element systems. The original research results reveal the possibilities of using such structures as basic elements for creating modern antenna-waveguide devices operating in the range from meter to millimeter wavelengths which have new technical characteristics and functionalities. This book is intended for senior and postgraduate students and researchers working in the fields of radiophysics, radio engineering and antenna-feeder design.

The book covers the following topics:

Excitation of Electromagnetic Fields in Electrodynamic Volumes with Coordinate Boundaries General Aspects of the Theory of Thin Impedance Vibrators and Narrow Slots in a Quasi-One-Dimensional Approximation Impedance Vibrators Antenna Arrays Slotted Waveguide Antenna Arrays Combined Vibrator-Slot Antenna Arrays Impedance Synthesis for Vibrator Antenna Arrays Impedance Synthesis for Slot Antenna Arrays Large-Aperture Rectenna Arrays of Wireless Power Transmission Systems Ultrawideband Combined Vibrator-Slot Antenna Arrays

Chapter 1. Excitation of Electromagnetic Fields in Electrodynamic Volumes with Coordinate Boundaries

Abstract

This Chapter briefly presents basic equations, boundary conditions and tensor Green’s functions for studying electromagnetic fields, which will be used throughout the book. This chapter with comments on some aspects of electrodynamics theory, will allow a reader to read the book without searching for additional references.

Chapter 2. General Aspects of the Theory of Multielement Systems of Thin Impedance Vibrators and Narrow Slots in a Quasi-One-Dimensional Approximation

Abstract

Let us formulate in the most general form the problem of excitation, scattering and radiation of electromagnetic fields by material bodies of finite size in the presence of the coupling holes between the two electrodynamic volumes. Let there be an arbitrary volume \(V_{1}\) bounded by a perfectly conducting, impedance, or partially impedance surface \(S_{1}\), some parts of which can be removed to infinity. The volume \(V_{1}\) is coupling with another arbitrary volume \(V_{2}\) through holes \(\Sigma_{n}\) \((n = 1,2 \ldots N)\) cut in the common surface between the two volumes. The boundary wall between the coupling volumes \(V_{1}\) and \(V_{2}\) has an infinitely small thickness in the region of the coupling holes.

Chapter 3. Impedance Vibrators Antenna Arrays

Abstract

Let us consider the system, consisting of \(N\) of the parallel impedance vibrators, located in free space. We introduce numeration of the vibrators and designate the length and the radius of the vibrator with the number \(n\) via \(2L_{n}\) and \(r_{n}\), correspondingly, and the corresponding coordinates of the vibrator centre in the Cartesian coordinate system—via \(z_{n}\), \(x_{n}\), \(y_{n}\).

Chapter 4. Slotted Waveguide Antenna Arrays

Abstract

At present time, a widespread type of antenna systems is represented by wave-guide-slotted antenna arrays (AA) [see, for example, 1–30] which have several ad-vantages over other antenna systems. These AA are characterized by following fea-tures: absence of protruding parts, simple excitation of AA with large number of radiators, and possibility to realize a wide range of amplitude-phase distribution of fields and currents over the AA aperture. This Chapter presents results concerning electrodynamic characteristics of some waveguide-slotted AA obtained by the au-thors.

Chapter 5. Combined Vibrator-Slot Antenna Arrays

Abstract

In this Section the dual-frequency antennas based on vibrator-slot structures with similar RP in main polarization planes are suggested. Such antennas can be realized by diode switching the activity of slot and vibrator elements. The traditional combined radiators with passive vibrators are proposed to use at the main frequency. The work at alternative frequency is provided by active vibrators. The formation of radiation fields by the combined structures at the main and alternative frequencies is analyzed.

Chapter 6. Impedance Synthesis for Vibrator Antenna Arrays

Abstract

In this Section a new method of impedance synthesis of antenna array radiation fields based on a single methodological conception is presented. At first, an approximate solution for the current in the thin vibrator with variable impedance was obtained using the partial averaging operation of the integral–differential equation.

Chapter 7. Impedance Synthesis for Slot Antenna Arrays

Abstract

In this Section a problem of impedance synthesis for a 2D antenna arrays consisting of narrow linear slots with magneto-dielectric filling is solved. The slots are cut in a perfectly conducting screen, which geometric centers coincide with nodes of a rectangular grid with double periodicity. The slots are excited by voltage δ-generators in the center of the slot apertures. The slot cavities are represented by rectangular resonators with magneto-dielectric filling which control the induced magnetic impedance of the radiators by varying the material parameters of the slots filling. The problem solution is based on the approach proposed by the authors for the impedance synthesis of vibrator arrays (Chap. 6) and based on the electrodynamic principle of permutation duality (Sect. 1.4.2).

Chapter 8. Large-Aperture Rectenna Arrays of Wireless Power Transmission Systems

Abstract

Rectennas are part of wireless power transmission (WPT) systems and are intended to receive microwave energy and convert it to DC energy. Efficiency of the WTP system is largely determined by the rectenna, which is an unphased array of receiver-rectifier elements (RREs), each of which consists of a receiving antenna and a rectifier circuit. Parameters of RRE mainly determine such indices of rectenna quality as efficiency, level of over-radiation at frequencies of higher harmonics, reliability, cost and suitability for serial production. Today, the optimization of both the parameters of individual RRE and the characteristics of the entire array as a whole remains relevant for the array. Of course, such optimization can be implemented only as a result of mathematical modeling.

Chapter 9. Ultrawideband Combined Vibrator-Slot Antenna Arrays

Abstract

Ultrawideband technologies are growing significantly in the last decades. The efforts were aimed at creating both efficient single impulse antennas, such as IRA (Baum in Radiation of impulse-like transient fields, pp 1–29, 1989 [1]; Baum et al. in Proc IEEE 92:1096–1109, 2004 [2]; Miletic and Olcan in IEEE Trans Antennas Propag 70:6414–6422, 2022 [3]), and antenna arrays. For example, there are MIMO communication systems that need to develop ultra-wideband antenna arrays.
