Variation in The Bandwidths of Pattern-Quality Parameters and Maximum Embedded Impedance among the Solutions to Shaped-Beam Synthesis Problems for Collinear Dipole Arrays
(Institute of Electrical and Electronics Engineers, 2003)
[Abstract] We investigated variation in the bandwidths of ripple, sidelobe level, -3 dB beamwidth, and maximum element embedded (active) impedance (|Z/sup e/|/sub max/) among multiple collinear dipole arrays radiating a ...
Very Fast Method to Synthesise Conformal Arrays
(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 ...
Analysis, Synthesis, and Diagnostics of Antenna Arrays through Complex-Valued Neural Networks
(John Wiley & Sons, Inc., 2006-08)
[Abstract] It is shown in this paper that when artificial neural networks are extended to be complex valued, they can be incorporated as a very powerful and effective tool in the analysis, synthesis, and diagnostics of ...
Avoiding Interference in Planar Arrays through the Use of Artificial Neural Networks
(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 ...
Optimizing Uniformly Excited Linear Arrays through Time Modulation
(Institute of Electrical and Electronics Engineers, 2004-12)
[Abstract] The letter shows that, by the proper use of time modulation in equispaced linear arrays with uniform excitation distribution, it is possible to maintain the sidelobe zone of the radiated power below a certain - ...
Perturbation of the Phases of Taylor Field Samples in the Synthesis of Linear and Circular Array Antennas
(Institute of Electrical and Electronics Engineers, 2004-12)
[Abstract] Antenna design specifications do not usually restrict the phase of the radiated field. Antenna synthesis techniques generally exploit this freedom only indirectly, but direct phase perturbation can be fruitful.
