CONFERENCE PREVIEW ANTENNA SYSTEMS 2013 11:20 am Antenna Radome Effects on High Performance SATCOM Antenna Systems Dr. Kozakoff, Chief Scientist - USDigiComm Corp. This presentation is a technical review of the antenna performance required for commercial SATCOM services as particularly applicable to mobile (maritime, airborne or vehicular) platform systems where dynamic antenna beam forming or pointing is required. Properly accomplished, these low sidelobe high performance antenna systems must take the antenna radome into account during the antenna design phase. Specifically, antenna parameters that will be modified by the presence of a radome include gain, depolarization, far-out sidelobe performance, antenna noise temperature, boresight error and registration effort (difference between uplink and downlink boresight error.) Some of these radome effects can be compensated for in the antenna design. 12:00 pm Networking Lunch 1:00 pm Space-Efficient UWB 2-D and 3-D Antenna Elements Dr. Anatoliy Boryssenko, Senior Scientist - A&E Partnership Attend this presentation to learn about several designs of UWB antennas implemented in 2-D printed circuit technology, 3-D volumetric fabrication and a hybrid mode using both 2-D and 3-D fabrication processes. For those antennas, optimal occupancy of physical space is achieved and measured with respect to supported lambda_ max. Design approaches, CAD modeling and numerical full-wave electromagnetic techniques used to advance performance of our antenna designs that can be used as single radiators, array elements or reflector feeds will be discussed. 1:40 pm Antenna Performance of LTE Enabled Hand-Held Tablets Derek Campbell, Application Engineer - EM Software & Systems (USA), Inc. LTE is one of the 4G mobile communication technologies developed at different frequencies. These frequencies range from 400 to 4,000 MHz with bandwidths up to 20 MHz. LTE utilizes multiple antennas on both ends of the wireless channel i.e. multiple-input-multiple-output (MIMO) to support high data rate 4G applications. Design challenges are not limited to miniaturized multi-band integrated antennas, but also include optimization of multiport matching networks, accounting for specific absorption rate (SAR) and the complex electromagnetic interaction between a mobile LTE device and the users, affecting antenna patterns and channel capacity. This presentation will show how these complicated and often conflicting challenges can be overcome. 2:20 pm MLFMA for Broadband Analysis of Antenna Systems Installed on Electrically Large Platforms Jonatan Aronsson, President - CEMWorks, Inc. Learn about a novel Multi-Level Fast Multipole Algorithm (MLFMA) that is suitable for broadband modeling of geometrically complex antennas that are mounted on electrically large platforms. Unlike the standard MLFMA formulation, the new algorithm can efficiently handle multi-scale features on electrically large models from low to multi-GHz frequencies. The improved performance is realized by utilizing spherical wave functions to expand the EM field. We will show that the method is applicable for electromagnetic analysis of composite metal-dielectric 3D models. 3:00 pm Networking Break in Exhibit Hall 3:40 pm Remote Antenna Site Failure Detection by Site Scanning Using AISG Modems Rick Dumont, Global Marketing Director - NXP Semiconductors NXP proposes a system called “Base station Site Scanning” or “Site Scan” – a reliable and scalable method to verify base station antenna site connectivity remotely, making use of intelligent connectors. Site Scan can be performed at any time under operating conditions without affecting the tower operation. We will explain how available antenna site technologies like AISG communication can be used to implement a complete Site Scan process, from mapping the tower equipment and connections, including equipment changes over time, to tracing connections, storing connectivity information and real-time tracing, repair, and verification of any antenna site connection and equipment failure. www.AntennasOnline.com/Conferences Register by October 10th for Discounted Rates 25 http://www.AntennasOnline.com/conferences
