Avoiding Interference in Planar Arrays through the Use of Artificial Neural Networks
Brégains, Julio; Dorado, Julián; Gestal, M.; Rodríguez, J. A.; Ares, F.; Pazos, A. (Institute of Electrical and Electronics Engineers, 2002-08)[Abstract] This article implements an artificial neural network to find, through computer simulation, the excitations of a square planar array. The array is composed of 52 uniformly spaced subarrays, and has a quasi- in ... -
Beam Reconfiguration of Linear Arrays Using Parasitic Elements
Rodríguez, J. A.; Trastoy, A.; Brégains, Julio; Ares Pena, F. J.; Franceschetti, G. (The Institution of Engineering and Technology, 2006-02-13)[Abstrac] An innovative method for linear arrays beam reconfiguration is presented. This pattern reconfigurability is achieved by a mechanical displacement of a parasitic array located in front of an active one. Two worked ... -
On the Multiplicity of Solutions of Taylor Linear Sources Generating Symmetrical Power Patterns with Filled Nulls
Brégains, Julio; Rodríguez, J. A.; Ares Pena, F. J.; Moreno Piquero, E. (Institute of Electrical and Electronics Engineers, 2004-12)[Abstract] As expressed in earlier works, if filled nulls are required in a power pattern generated by a Taylor line source, their corresponding roots must be complex. This leads to a multiplicity of solutions emerged from ... -
Optimal Synthesis Of Circular Apertures Based On Ludwig Distributions
Brégains, Julio; Rodríguez, J. A.; Ares Pena, F. J.; Moreno Piquero, E. (Taylor & Francis, 2003-01)[Abstract] Ludwig distributions are a generalization of circular Taylor distributions that generate radiation patterns with wide-angle side lobe levels decaying faster than for Taylor patterns. In this paper we show that ... -
Optimal Synthesis of Line Source Antennas Based On Rhodes Distributions
Brégains, Julio; Rodríguez, J. A.; Ares Pena, F. J.; Moreno Piquero, E. (Taylor & Francis, 2002)[Abstract] In this paper we show that by means of an appropriate optimization technique the zeros of Rhodes radiation patterns can be perturbed so as to improve or modify pattern and/or the aperture distribution characteristics ... -
Very Fast Method to Synthesise Conformal Arrays
Fondevila, J.; Rodríguez, J. A.; Brégains, Julio; Moreno Piquero, E.; Ares Pena, F. J. (The Institution of Engineering and Technology, 2007-08-02)[Abstract] A very fast technique that allows the synthesising of arbitrary footprint patterns by using conformal arrays with many radiating elements is described. This method is based on a combination of Woodward-Lawson ...
