Variation in Bandwidths Among Solutions to Shaped Beam Synthesis Problems Concerning Linear Arrays of Parallel Dipoles
(Institute of Electrical and Electronics Engineers, 2005-01)
The problem of synthesizing a linear array generating a shaped beam pattern with M filled s has 2M alternative solutions. In this study we examined their bandwidths as regards compliance with pattern quality or input ...
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 ...
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 ...
