Dual-band dual-polarized array for WLAN applications

Author: Steyn, JM ; Odendaal, JW ; Joubert, J Date: 2009 Paper presents a dual-band dual-polarized antenna array design for WLAN applications. Four double-dipole elements are orthogonally interleaved to facilitate operation in both the standard WLAN frequency bands (IEEE 802.11b and IEEE 802.11a) ... Read more
Efficient synthesis of large-scale thinned arrays using a density-taper initialised genetic algorithm

Author: Du Plessis, WP Date: Sep 2011 The use of the density-taper approach to initialise a genetic algorithm is shown to give excellent results in the synthesis of thinned arrays. This approach is shown to give better SLL values more consistently than using random values and ... Read more
Method of applying single higher order polynomial basis function over multiple domains

Author: Lysko, Albert A Date: Mar 2010 A novel method has been devised where one set of higher order polynomial-based basis functions can be applied over several wire segments, thus permitting to decouple the number of unknowns from the number of segments, and so from the geometrical ... Read more
Modelling of coil-loaded wire antenna using composite multiple domain basis functions

Author: Lysko, Albert A Date: Mar 2010 The paper discusses aspects of a novel impedance matrix compressing technique and applies the technique to a coil-loaded monopole. The technique can reduce the number of variables required for modelling of structures with curvatures and ... Read more
