Course Highlights:
This workshop focuses on the fundamental principles of antenna theory for the characterization and design of various antennas used in modern wireless communication systems. It is designed for practicing engineers, research scientists, technologists and engineering managers in the fields of wireless communications, antennas and propagation, navigation, radar, remote sensing, and radio astronomy who require a better understanding of antenna analysis, design, and measurement techniques. A basic introductory knowledge of electromagnetic theory is assumed.

The workshop begins with elementary principles, develops underlying concepts, and progresses to advanced modeling tools and antenna configurations. Procedures and practical examples are given for designing wire antennas, microstrip patch antennas, and horn antennas. Participants will get hands-on experience with design and testing of various antennas commonly used in today’s communication systems.

Who Should Attend:
This workshop is primarily meant for practicing engineers, research scientists, and technologists
who deal with antenna design and measurement. The course is application oriented with lots of
practical design examples and provides hands-on session. The course can also be useful for college
instructors who teach antenna analysis and design. Professionals and managers who are involved in
decision-making, analysis and design of wireless communication systems should find this course
beneficial as well.
