We demonstrate a novel fabrication approach for high-throughput fabrication of engineered infrared plasmonic nanorod antenna arrays with Nanostencil Lithography (NSL). NSL technique, relying on deposition of materials through a shadow mask, offers the flexibility and the resolution to fabricate radiatively engineer nanoantenna arrays for excitation of collective plasmonic resonances. Overlappin...

The use of fractal geometries has significantly impacted many areas of science and engineering; one of which is antenna. Designing antenna using fractal geometries has been shown to improve several antenna features. Moment method based simulation code was applied to perform a detailed parametric study for H-Shape model. The use of this model reduces the size of a resonant antenna compared with ...

A new design and experimental results of a microstripfed ultra-wideband Fermi antenna at millimeter-wave frequencies are presented. By utilizing a new microstrip-to-CPS balun (or transition), which provides wider bandwidth than conventional planar balun, the design of microstrip-fed Fermi antenna is greatly simplified. The proposed Fermi antenna demonstrates ultra-wideband performance for the f...

In this paper, we propose a localization method using iterative angle of arrival (AOA) method sharing snapshots of coherent subarrays. The conventional AOA method is restricted in some applications because array antenna used for receivers requires many antennas to improve localization accuracy. The proposed method improves localization accuracy without increasing elements of antenna arrays, and...

With the advance of wireless communication systems and increasing importance of other wireless applications, wideband and low profile antennas are in great demand for both commercial and military applications. Multi-band and wideband antennas are desirable in personal communication systems, small satellite communication terminals, and other wireless applications. Wideband antennas also find app...

This paper considers the joint application of neural networks and antenna array systems in mobile, satellite and sensor systems. The main assumption is that there is a possibility of a large number of neurons in the network according the fact that the human brain uses a huge number of neurons. Results of detail analyze for signal detection, direction of arrival estimation, and beamforming are p...

In this paper, we intend to study the synthesis of the multibeam arrays. The synthesis implementation’s method for this type of arrays permits to approach the appropriated radiance’s diagram. An adaptive particle swarm optimization algorithm (APSO) is proposed to synthesis multibeam antenna arrays. The problem is formulated and solved by means of the proposed algorithm. The examples are simulat...

The estimation of code delays along with amplitudes and phases of di erent users constitutes the rst stage in the demodulation process in a CDMA communication system. The delay estimation stage is termed the acquisition stage and forms the bottleneck for the detection of users' bitstreams; accurate detection necessitates accurate acquisition. Most existing schemes incorporate a single sensor at...

In this paper, an efficient implementation of the spectral domain moment technique is presented for computing the self and mutual coupling between slot antennas on a dielectric half-space. It is demonstrated that by the proper selection of the weighting functions in the method of moments, the analytic evaluation or simplification of the transverse moment integrals is enabled. This results into ...
