Beam steering for circular switched parasitic arrays using a combinational approach

Author: Mofolo, ROM ; Lysko, Albert A ; Olwal, TO ; Clarke, WA Date: Sep 2011 In this paper, the authors present a method of electronic beam steering for circular switched parasitic array (SPA) antennas. In circular SPA antennas, one achieves azimuth beam steering by open-circuiting and short-circuiting different ... Read more
Calculation of radiation field integrals for higher-order basis functions in conical thin wire MoM formulation

Author: Lysko, Albert A Date: Jul 2008 An efficient method of integration for far field calculations is derived. The method applies to the integrals arising from calculation of far field pattern with higher-order polynomial basis functions and moment method. The integral under ... Read more
Polarization diverse antenna for dual-band WLAN applications

Author: Steyn, JM ; Joubert, J ; Odendaal, JW Date: Oct 2009 A dual-band dual-polarized (DBDP) configuration is proposed for wireless local area network (WLAN) applications. A four-element array is used to facilitate operation in both the standard WLAN frequency bands (IEEE 802.11b and IEEE 802.11a) ... Read more
