2002 9th International Symposium on Antenna Technology and Applied Electromagnetics, 2002
There is an increasing requirement to make devices smaller and at the same time interconnect them on a wireless network. One of the main challenges in the production of small wireless devices is the design of an antenna small enough to fit on the device and yet have good performance. Size reduced microstrip antenna are good candidates for this application; ...

A helical beam antenna with uniform conductor size has a nominal impedance of 140 ohms. This may not be convenient for some applications. The purpose of this note is to call attention to the fact that the impedance can be adjusted to 50 ohms by increasing the conductor size close to the feed point at the ground plane. This lowers ...
IEEE Potentials, 1999
Today, most antenna designs are simulated numerically rather than analyzed theoretically. A computer program approximates the structure and calculates its properties. Even though very complex designs can be simulated, structures are usually kept simple to allow for easy understanding and analysis. Symmetry is often present. Nearly all the designs "make sense" when one looks at them or their circuit schematics. ...
2016 11th International Symposium on Antennas, Propagation and EM Theory (ISAPE), 2016
A dual-polarized Yagi-Uda antenna for the passive radar is proposed. The antenna consists of two orthogonally installed Yagi-Uda antennas, each of them responsible for one polarization direction. The measurement result shows that the cross polarization discrimination between the two ports is more than 20dB. Antenna patterns for both polarization directions are the same due to the symmetric structure. Experiment for ...

There is an increasing requirement to make devices smaller and at the same time interconnect them on a wireless network. One of the main challenges in the production of small wireless devices is the design of an antenna small enough to fit on the device and yet have good performance. Size reduced microstrip antenna are good candidates for this application; however, the size of the ground plane is a major impediment to its successful implementation. This paper will discuss the negative effects of reducing the size of the ground plane of a microstrip antenna and provide a unique solution to improving small antenna performance.
A helical beam antenna with uniform conductor size has a nominal impedance of 140 ohms. This may not be convenient for some applications. The purpose of this note is to call attention to the fact that the impedance can be adjusted to 50 ohms by increasing the conductor size close to the feed point at the ground plane. This lowers the characteristic impedance of the conductor-ground plane combination (acting as a transmission line) and transforms the helix impedance to a lower value over a substantial bandwidth
Today, most antenna designs are simulated numerically rather than analyzed theoretically. A computer program approximates the structure and calculates its properties. Even though very complex designs can be simulated, structures are usually kept simple to allow for easy understanding and analysis. Symmetry is often present. Nearly all the designs "make sense" when one looks at them or their circuit schematics. This is not necessarily the case for antennas designed using a genetic algorithm (GA). We illustrate this automated design technique on two types of wire antennas. The first is a Yagi-type antenna that is optimized to have different electromagnetic characteristics from a conventional Yagi. The second is radically different from a typical antenna: a seemingly arbitrary structure of seven wires connected in a series and confined to a specified volume; the actual shape is completely determined by the GA.
A dual-polarized Yagi-Uda antenna for the passive radar is proposed. The antenna consists of two orthogonally installed Yagi-Uda antennas, each of them responsible for one polarization direction. The measurement result shows that the cross polarization discrimination between the two ports is more than 20dB. Antenna patterns for both polarization directions are the same due to the symmetric structure. Experiment for target detecting is conducted with the help of this dual-polarized antenna. Signal processing results show that SNR has been improved through the polarized enhancement technology. Thus Yagi-Uda antenna is a good choice to take into consideration when making dual-polarized antenna for passive radar.
Numerical data for the design of uniform coaxial Yagi arrays of circular loops are presented. For the given data the electrical dimensions of the exciter and the reflector combination are selected to be optimum for the directive gain in the forward direction.
This paper investigates the introduction of nano-sized Ag cluster into a SiO/sub 2/ matrix by Ag/sup +/ implantation on thermally oxidised SiO/sub 2/ layers. The embedded Ag nanoclusters create conducting paths for the emissive electrons from substrate to emission surface and give rise to a local electric field enhancement due to an electrical inhomogeneity effect.
In this paper, a high gain yagi-uda Origami antenna is introduced. Antenna is realized on a paper substrate by using origami tetrahedron structure. The radiating aperture comprises a triangular shaped monopole and two strip directors. The proposed antenna is verified by simulation and measurement results. The fabricated antenna demonstrates a peak gain of 9.6dBi at 2.6 GHz with impedance bandwidth of 66% (2-4 GHz).
This paper presents a linearly polarized Yagi-Uda patch antenna deployed with rectangular parasitic elements. In this work, the effect of shorting location or switching location towards the performance of beam tilt angle and reflection coefficient is investigated. By varying the shorting location, the direction of a main beam can be tilted to various angles. However, since the beam patterns overlap with each and other, only four shorting locations are proposed to achieve three sets of directive beam patterns which have maximum separation between them. The antenna is capable to steer the main beam to three different directions at theta of +30°, 0° and -30° at H-plane while sustaining a constant reflection coefficient bandwidth of 274 MHz around center frequency of 5.8 GHz. Operating around 5.8 GHz frequency, this antenna is capable to be used for WIFI and WIMAX applications.
Nanoantennas have demonstrated unprecedented capabilities for manipulating the intensity and direction of light emission over a broad frequency range. The directional beam steering offered by nanoantennas has important applications in areas including microscopy, spectroscopy, quantum computing, and on-chip optical communication. Although the Kerr effect has been explored to control the far-field radiation of nonlinear antennas, the design of the nonlinear antennas is similar to that of linear counterparts due to the dominating local-bulk dipolar mode in small metallic nanoparticles. Different from the Kerr effect, the second harmonic radiation from the metallic nanoparticle shows a complex surface-induced multipolar interaction without the local-bulk dipolar mode. Moreover, the far-field second harmonic radiation obeys a number of selection rules strongly relying on the symmetry and surface characteristics of the nanoparticle. In the work, we propose a novel nonlinear Yagi-Uda nanoantenna to direct second harmonic radiation from a metallic nanosphere. The Love's equivalence principle and self-consistent boundary element method, which capture the pump depletion and cross coupling between the fundamental and second harmonic fields, are employed to model the dielectric-metal composite nanoantenna. By carefully tuning the spacing and dimensions of two lossless dielectric elements, which function respectively as a compact director and reflector, the second harmonic radiation is deflected 90 degrees with reference to the incident light (pump) direction. This abnormal light-bending phenomenon is due to the constructive and destructive interference between the second harmonic radiation governed by a special selection rule and the induced electric dipolar and magnetic quadrupolar radiation from the two dielectric antenna elements. Simultaneous spectral and spatial isolation of scattered second harmonic waves from incident fundamental waves pave a new way towards nonlinear signal detection and sensing.
