Superstrate embedded hybrid MHD antenna

2015 Annual IEEE India Conference (INDICON), 2015
This paper presents the complete implementation of superstrate embedded dielectric resonator antenna on patch. The hybrid structure is operated under controlled electric field and magnetic field. The design is loaded with superstrate. The Meta material fluid is filled in two concentric cylindrical DRA and it is placed on annular copper etched ring. The

A novel multifrequency hybrid antenna

Microwave and Optical Technology Letters, 2013
ABSTRACTA hybrid multifrequency antenna is designed by using a cubic dielectric resonator antenna and coplanar wave guide (CPW) loop radiator. The dielectric resonator antenna (DRA) is also excited by the same CPW. The DRA in conjunction with the CPW loop generates multiple frequencies which may be controlled by optimizing the dimension of the DRA and ...

Hybrid Reflector-Array Antenna Concept

2006 IEEE Antennas and Propagation Society International Symposium, 2006
This paper describes a concept for a hybrid antenna that combines the conventional reflector with an array of printed circuit elements that uses the reflector surface as the array aperture. The objective is to increase the gain and the functionality of the antenna by reusing the conical surface of the reflector as a direct radiating array.

Adaptive nulling in hybrid antennas

Proceedings of IEEE Antennas and Propagation Society International Symposium, 2002
Adaptive nulling in an array-fed offset paraboloidal reflector is considered. A narrow band system is assumed. It is also assumed that the signals received from the array feed can be weighted in both amplitude and phase and then summed to form the array output. The particular adaptive nulling algorithm used here is the generalized sidelobe canceller. H-

Hybrid optical antenna with high directivity gain

SPIE Proceedings, 2013
Coupling of a far-field optical mode to electronic states of a quantum absorber or emitter is a crucial process in many applications, including infrared sensors, single molecule spectroscopy, and quantum metrology. In particular, achieving high quantum efficiency for a system with a deep subwavelength quantum absorber/emitter has remained desirable. In

“The Hybrid Ring Loop Antenna”

2019 International Workshop on Antenna Technology (iWAT), 2019
A full wave circular loop antenna is configured as a hybrid ring loop antenna to provide linear polarization, circular polarization, dual linear polarization and dual circular polarization. The radiating structure is a circle of thin wire near one wavelength in circumference with gap ports.

Investigation of hybrid Hexagonal antenna arrays for Smart antenna Applications

2018 3rd International Conference on Communication and Electronics Systems (ICCES), 2018
In this paper, presented two novel types of antenna arrays constructed from combination of linear and hexagonal antenna arrays for smart antenna applications. These types are concentric hexagonal and hexagonal cylindrical antenna arrays. Antenna elements are uniformly distributed and excitation amplitude coefficients are computed using firefly ...

H2QL: A novel hybrid antenna

The 17th Asia Pacific Conference on Communications, 2011
H2QL stands for hybrid dual quad loop. This paper describes the novel antenna with respect to antenna impedance, gain and standing wave ratio. These three parameters are simulated using EZNEC+ v5.0 at different diameter of elements, separation of loops, and length of concentrator.

Hybrid MoM/PO Antenna Modelling

9th IET International Conference on Computation in Electromagnetics (CEM 2014), 2014
Results of modelling antennas installed near electrically large platforms using a hybrid method-of-moments/physical optics code are reported here. A half-wavelength wire monopole driven by a delta-gap voltage source was positioned in two locations on a representative ship on a ground plane.
