Resumen

A synthesis method to design multielement antennas with couplings is presented. The main objective is to perform a rigorous determination of the electromagnetic characteristics involved in the design, especially with arrays of moderate sizes. The aim is to conceive jointly and efficiently the antenna and the circuits to connect (feed distribution network, power amplifiers, reactive loads, etc.). The subsequent objective is to improve the understanding and capabilities of strongly coupled antennas. As a whole, the synthesis procedure is then applied to different antenna architectures in order t

Resumen

The magnetoelectric (ME) antennas rely on the mechanical movement of magnetic dipoles, making it possible to break the constraints on physical dimensions decided by the wavelength of the electromagnetic wavelength. The ME antennas achieve super-low frequency (SLF) communications with a smaller size to provide a novel solution for long-range, underwater, and underground communications; navigation over the horizon; and geological exploring. As a result, further theoretical research and optimization of ME antennas have been an open challenge for decades. Here, we report on minitype arrays of acou

The paper discusses the features of the application of the ESPRIT method, which provides direction finding of a variety of radio sources with minimal computational costs, including in real time. To be able to use ESPRIT, antenna arrays are required that have the property of shift invariance, and for practical implementation, antenna arrays are required that allow you to form estimates of the directions of arrival of the largest number of signals that overlap in the spectrum, with a minimum number of antennas and reception channels.

Resumen

Conformal antennas and antenna arrays (arrays) have become necessary for vehicular communications where a high degree of aerodynamic drag reduction is needed, like in avionics and ships. However, the necessity to conform to a predefined shape (e.g., of an aircraft’s nose) directly affects antenna performance since it imposes strict constraints to the antenna array’s shape, element spacing, relative signal phase, and so forth. Thereupon, it is necessary to investigate counterintuitive and arbitrary antenna shapes in order to compensate for these constraints. Since there does not exist any avail

Microstrip antennas are antennas that are often applied because of their simple structure and easy to apply. The purpose of the experiment was to design and analyze the results of microstrip antennas in CST applications with a frequency of 10.5 GHz. Experiments used single patch antennas, 1 x 2 arrays using 2 patches and 1 x 4 antenna arrays using 4 antenna patches. Each series has different characteristics of return loss, gain, VSWR, and axial ratio.

Resumen

Antenna arrays are systems that consist of a large number of antenna elements to shape, steer, and direct the beam without any physical motion of the antenna. Their basic concept is to use a group of separate antennas, each element of which can change the phase or amplitude of the radiated signal. This makes it possible to direct radiation and control the angle of the main lobe of the antenna system's radiation pattern. The use of antenna arrays is widespread in many areas, such as military radars, satellite communications, security systems, the Internet of Things (IoT), and mobile communicati

Resumen

For human head magnetic resonance imaging at 10.5 tesla (T), we built an 8-channel transceiver dipole antenna array and evaluated the influence of coaxial feed cables. The influence of coaxial feed cables was evaluated in simulation and compared against a physically constructed array in terms of transmit magnetic field (B1+) and specific absorption rate (SAR) efficiency. A substantial drop (23.1% in simulation and 20.7% in experiment) in B1+ efficiency was observed with a tight coaxial feed cable setup. For the investigation of the feed location, the center-fed dipole antenna array was compare

This article comparatively shows the evolution of parameters of three types of arrays for MIMO microstrip antennas, to which the number of ports is gradually incremented until reaching 32. The three arrays have a 1 × 2 configuration in each port and present different geometry or type of coupling in the next way: square patch with quarter-wave coupling (Antenna I), square patch with inset feed (Antenna II) and circular patch with quarter-wave coupling (Antenna III).

Resumen

Designing an ultra-wideband array antenna for fifth generation (5G) is challenging for the antenna designing community because of the highly fragmented electromagnetic spectrum. To overcome bandwidth limitations, several millimeter-wave bands for 5G and beyond applications are considered; as a result, many antenna arrays have been proposed during the past decades. This paper aims to explore recent developments and techniques regarding a specific type of phased array antenna used in 5G applications, called current sheet array (CSA). CSA consists of capacitively coupled elements placed over a gr

Resumen

The design of isolators to reduce mutual coupling in large two-dimensional antenna arrays is complex and requires significant computational effort. This work attempts to alleviate this problem by applying different types of planar isolators in different orientations and experimenting first with two-element microstrip antenna arrays. A U-shaped planar transmission line isolator, a U-shaped planar transmission line-based destructive ground structure, and a planar neutralization line structure are designed to reduce E-plane or H-plane coupling in two-element microstrip antenna arrays.

This paper presents the numerical studies of the bowtie antenna with and without metasurface in cross-coupled arrays. The single bowtie antennas coated by the metasurface are designed at the neighboring frequency of 3 GHz. The cloaked frequency of the cloaked bowtie antennas is controlled by components that consist of metasurface such as the dielectric constant of the supporting material, slot width, spacing of the slot, and the height of the material. The cloaked bowtie antenna has characteristics such as the minimum reflection from the antenna at the designed frequency and, at the same time
