Abstract: This short course gives the participants an overview of the application, implementation, design and verification of base station antennas for 5G. In particular it is aimed at microwave, RF- and antenna engineers in the wireless area, but also useful for researchers looking for relevant research topics and system engineers needing a deeper understanding of the antenna component of their system.
The course explains underlying theoretical and practical implementation aspects of base station antennas in mobile communication networks of today and in 5G networks but discusses also their design, requirements and verification.
Outline: The course is divided into eight parts:
In the first three parts the fundamental parameters of a base station antenna are discussed in the context of radio network design. In particular we discuss parameters such as gain, radiation patterns, frequency bands and beam forming and put them in the context of cell planning, propagation and capacity.
In the fourth and fifth parts of the course we give an overview of the underlying theory of diversity, MIMO and multi beam antenna systems. In particular we look in detail at the implementation of multiple antennas in the 3GPP standard and how it is supposed to be used in various scenarios of 5G
In the final parts, we discuss the design of advanced antenna systems (AAS), regulatory requirements and their verification. In particularly we discuss “Over the Air” verification methods such as: Far field measurements (incl. CATR), Near field measurements and the use of, Reverberation chambers.

Abstract: Electromagnetic metamaterials are artificial periodic structures engineered to control the propagation of waves and to achieve physical effects not attainable in natural materials – high-frequency magnetism, negative refraction, strong absorption, lensing, cloaking, and more. Research in metamaterials started three decades ago, if not earlier, and exploded in the 2000s as a quest for “perfect lenses,” “perfect absorbers,” etc. But, as the field of metamaterials matured, it became clear that ideal devices were not realizable because of losses, finite lattice cell sizes, and other factors. Undoubtedly, however, “imperfect” materials and devices will continue to be developed, and we can therefore expect a growing need for more sophisticated methods of their analysis and, more specifically, for accurate homogenization theories valid for any composition and size of the lattice cell.
The objective of homogenization (effective medium theory) is to describe a composite structure in terms of effective parameters accurately representing reflection, transmission and propagation of waves on the scale coarser than the lattice cell size.
The course introduces a homogenization methodology valid in both electrostatics and electrodynamics and applicable to an arbitrary size and composition of the lattice cell. Nonlocal effects can be included in the model, making order-of-magnitude accuracy improvements possible. We then travel backward in time and explore the connection between the new framework and the classical 19th – early 20th century theories of Clausius-Mossotti, Lorenz-Lorentz, Maxwell Garnett.
A particularly challenging problem for future research is to determine what effective material tensors are attainable for given constituents of a metamaterial with their given properties, and how the lattice cell could be designed to produce such tensors. For example, what is the maximum effective permeability achievable? Bounds for effective parameters are currently known only for relatively simple settings, such as static dielectric permittivity of mixtures with two ingredients. The methodology developed in this course may help to make progress toward solving a much broader set of problems of this kind. This methodology can also be extended to other areas – for example, acoustics or eddy current problems in laminated cores of electric machines.

Abstract: The main disadvantage with forming a beam in a specific direction using an array antenna is that it requires multiple radiation elements, phase shifters, and signal processing circuits. The size, weight, and cost of such an antenna prohibit its use in modern portable transceivers. This short course describes how to overcome such issues, presenting recent progress in beamforming antennas. The course is composed of three chapters.
Chapter 1 describes beam-forming antennas that are fabricated using conventional natural materials. Each antenna is composed of a main radiation element and parasitic elements. A detailed discussion of beam forming in 2, 4, and 16 directions is presented. The presentation reveals the reconfigurablity of the antenna characteristics, and includes the radiation pattern, input impedance, and gain, when the beam is steered around the antenna axis. Note that the radiation from these antennas is linearly polarized (LP).
Chapter 2 introduces circularly polarized (CP) beam-forming metamaterial antennas that can steer their beam in both the azimuth and elevation planes. The antenna height is chosen to be extremely small: on the order of lambda/100 at the operating frequency. This makes these antennas suitable for installation on the surface of moving objects, such as vehicles and satellites.
Chapter 3 presents high-gain antennas with a beam that can be tilted in specific directions. It is emphasized that these antennas do not use phase shifters; each antenna is composed of a single radiation source and N (= 1, 2, 3) inhomogeneous loop-based metaplates, which are placed above the radiation source. The mechanism for forming a tilted beam is explained and radiation beams with a tilt angle of 30 and 60 degrees from the zenith are demonstrated.

Abstract: The proliferation of wireless market has driven the demand of smart RF systems with multi-functional sensing, energy harvesting and communication modules that can readily reconfigure their electromagnetic response depending on changes in their environment. This requires low-cost, compact, flexible and reconfigurable RF components that can be printed on-demand and scaled-to-large numbers. However, current systems are inadequate to meet these demands which can be largely attributed towards use of - 1) subtractive manufacturing technologies (SMTs) and 2) conventional tunability schemes that become non-linear and complicated as structure size increases.
Traditional SMTs are complicated, require specialized clean room environment and can only realize planar RF modules with high fabrication cost & time and moderate achievable performance. Moreover, their planar configuration can only support finite tunability mechanisms that can be broadly categorized into changing material properties, using complex electronics or micro-electromechanical (MEMS) structures. These techniques are typically power hungry, laborious, expensive with limited (discrete-state) tunability range making them impractical as the size of the structure increases. In comparison, mechanical tuning mechanisms features superior power handling capability, quality factor, linearity and wide-band (continuous range) tunability but their bulky size, heavy weight and low switching/tuning speed has restricted their use in modern communication systems.
The hidden link between the two approaches are smart 4D origami-inspired RF structures; that are designed to mimic nature's wisdom of self-assemblage and shape-reconfiguration in a well-studied and controlled manner to achieve tunability through shape-morphing.
