This letter reports the concept and development of the first optically controlled reconfigurable antenna formillimeter-wave (mm-wave) applications. It is based on a slotted-waveguide antenna array and two photoconductive ...

This paper uses artificial neural networks (ANN) to compute the resonance frequencies of rectangular microstrip antennas (MSA), used in mobile communications. Perceptron Multi-layers (PML) networks were used, with the ...

This paper presents the simulation, fabrication and complete characterization of a 2.4 GHz directional antenna designed for Wireless Sensor Network (WSN) nodes, named SPIDA. The use of this kind of antennas empowers the ...

The work investigates the electromagnetic performance of omnidirectional dual-reflector antennas designed to operate with a frequency bandwidth larger than 45% (25-40 GHz). We consider two antenna configurations, distinguished ...

A new excitation model for the numerical solution of field integral equation (EFIE) applied to arbitrarily shaped monopole antennas fed by coaxial lines is presented. This model yields a stable solution for the input ...

We present a novel approach to design a high-performance tapered slot antenna (TSA) at millimeter-wave frequencies. Commonly, TSAs are designed using profiles expressed as simple functions (linear, exponential, Fermi, or ...

Conformal techniques, based on the covariance of Maxwell's electrodynamics under the full conformal group in four spacetime dimensions, are discussed in relation with the constant input impedance properties of frequency- ...
