Course Overview

Course in a Nutshell

From base stations to mobiles and microwave dishes to radars, antennas are a pervasive and important element of all RF systems.  What are the features that characterize an antenna, whether transmitting or receiving? How does the system performance depend on these antenna characteristics? How should one select, configure, and mount an antenna to effectively serve current needs as well as future demands? How are the evolving (e.g., 4G wireless and beyond) radio technologies influencing and are being influenced by the ever increasing complexity and sophistication of antennas? These and other questions are the subject of this important course. The answers will help you exploit antennas more effectively, whether you’re designing a new network, optimizing an existing one, or migrating it to a new technology.


Customize It!

Customize this course at little-to-no additional cost to your specific needs. You may tailor it to type of radio system you work with, whether 3G or 4G+ wireless/cellular, WiFI, WiMAX, HF/UHF, microwave, radar, or military. You may also adapt it to your intended audience, e.g., network design and optimization engineers, equipment or application designers, equipment installers, and less technical audiences such as in deployment, sales and marketing, and operations and support.
For an integrated treatment of RF propagation and antennas, combine this course with RF Propagation Models, Fading Characteristics, and Link Budget (RFPROP, 3 days).
