Progress in the Development and Applications of Huygens Dipole Antennas and Huygens Dipole Antenna Arrays

2021 Fifteenth International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials), 2021
Electrically small Huygens dipole antennas and their unidirectional radiation properties and their applications will be reviewed. Examples of the progress in realizing multifunctional and reconfigurable Huygens source designs will be described. Applications such as wireless power transfer (WPT) and wirelessly powered sensors will be discussed.

The Parametric Optimization of Wire Dipole Antennas

IEEE Transactions on Antennas and Propagation, 2011
The shape representation of planar wire dipole antennas of fixed radius is discussed. Away from the feed point the shape can be always represented as a arc-length parametrizable Lipschitz-continuously differentiable curve. The representation is applied to classical directivity optimization design problems as well as impedance optimization problems.

Printed Dipole Antenna with Stepped-Width Dipoles

2020 1st International Conference Problems of Informatics, Electronics, and Radio Engineering (PIERE), 2020
The new printed dipole antenna is presented in the paper. The main advantage of the antenna in comparison with classic printed dipole antenna is a small length of dipoles due to their stepped configuration. The antenna works at two central frequencies simultaneously and can be used both as a standalone antenna and as a part of antenna arrays.

Transient Response of a Dipole Antenna

Journal of Mathematical Physics, 1962
The transient current in a long dipole antenna excited by a step-function voltage across an infinitesimal center gap has recently been calculated by Wu. A simpler derivation of Wu's result is given using double Fourier transformation.

The terminal voltage of a receiving dipole antenna

IEEE Transactions on Antennas and Propagation, 1984
The terminal voltage of a receiving dipole antenna is dependent on the antenna current distribution which in turn is dependent on its feed-point load impedance.

3D-fractal rectangular Koch Dipole and Hilbert Dipole antennas

2007 IEEE Antennas and Propagation International Symposium, 2007
3D-fractal rectangular Koch dipole and 3D-fractal Hilbert dipole antennas made of wires are introduced. Theses antennas exhibit lower resonant frequencies and small volume occupations. The performance characteristics of the proposed antennas are examined and compared with successive iterations for the same antenna height for the 3D-fractal rectangular ...

A generalized crossed dipole antenna, the Fourtear antenna

IEEE Antennas and Propagation Society Symposium, 2004., 2004
A generalized form of a crossed dipole antenna, the Fourtear antenna, has been designed and tested. The Fourtear antenna is a promising dual-polarized broadband antenna element. The antenna consists of four identical teardrop elements, but the horizontal elements are positioned perpendicular to the vertical elements. The radiating element is printed on

Experiments with dipole antennas

European Journal of Physics, 2009
Employment of a data-acquisition system for data collection and calculations makes experiments with antennas more convenient and less time consuming. The determined directional patterns of the dipole antennas of different lengths are in reasonable agreement with theory.
