Design of Reconfigurable Array Antennas With Minimum Variation of Active Impedances
(Institute of Electrical and Electronics Engineers, 2006-12)
[Abstract] In this letter, the authors propose an optimization method based on the genetic algorithm (GA) to reconfigure a linear array of vertical half-wavelength dipole antennas to generate two patterns with minimum ...
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 ...
Beam Reconfiguration of Linear Arrays Using Parasitic Elements
(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 ...
Application of Time Modulation in the Synthesis of Sum and Difference Patterns by Using Linear Arrays
(John Wiley & Sons, Inc., 2006-05)
[Abstract] In this paper, time modulation is applied to a small number of elements of a linear array that radiates either sum or difference patterns, in order to take control over their sidelobe levels. The simulated ...
