Smart Antennas is an extensive course sequence on the theory and background behind adaptive antennas that are capable of changing beam pattern and performance according to user specified criteria. These antennas have application in radio direction finding, radar, HF, adaptive arrays, cognitive antennas, jammer nulling, search for extra-terrestrial intelligence (SETI), stealth applications, shipboard and platform based arrays, and Active Electronically Steered Arrays (AESA) to name a few.
This 8 class sequence will be based on the Smart Antenna book and Frontiers in Antennas book written by Dr. Frank Gross as well as other relevant modern radar and antenna books.
Each session will be presented LIVE by an actively engaged instructor. The virtual classroom allows you to “raise your hand,” ask your questions audibly or type them in the chat, and the instructor will respond to your questions in real-time. It’s just like sitting in the classroom with the instructor – all without leaving your office or home. All sessions are recorded and are made available to registrants for 30 days after registering. Recordings are available within 24 hours.
Session 1 – Overview of Smart Antennas
September 6 - 1300-1600 EDT (1700-2000 UTC)
Smart Antennas are antennas that adaptively react to any environment so as to allow optimum performance under varying conditions. An overview of Smart Antennas will be given so that the participant understands the value of this growing technology.

Session 2 - Early Smart Antennas/Direction Finding
September 8 - 1300-1600 EDT (1700-2000 UTC)
”Smart Antennas” date back to the 1950’s in regards to HF direction finding. A summary of early smart antennas will be given to help explain early limitations in performance but also to explain the early development of this valuable technology.

Session 3 - Smart Switched Beam Antennas
September 11 - 1300-1600 EDT (1700-2000 UTC)
“Switched Beam” antennas are the next logical evolution of antenna arrays. This technology allows an array to search discrete “zones”. A full explanation of this technology helps to undergird modern automated approaches.

Session 4 - Smart Reconfigurable Antennas
September 13 - 1300-1600 EDT (1700-2000 UTC)
Reconfigurable antennas are those that change their geometry so as to react to changing environments. This is a form of antenna “Shape Shifting”. The switching is automated so that a user does not have to be in the loop.

Session 5 - Smart Reconfigurable Antenna Surfaces
September 18 - 1300-1600 EDT (1700-2000 UTC)
Smart surfaces are a unique way of changing the antenna pattern, not by steering a beam, but by changing the substrate so that the beam is effectively steered. Examples of this approach are given including the use of “metamaterials”.

Session 6 - Cognitive Antennas
September 20 - 1300-1600 EDT (1700-2000 UTC)
Cognitive Antennas are smart by using “Cognitive” switching of antenna elements in a larger more complex structure. This is a form of an adaptive antenna but where the antenna continuously reconfigures it’s own geometry.

Session 7 - Smart Vector Antennas
September 25 - 1300-1600 EDT (1700-2000 UTC)
Vector antennas are unique in that they can determine angles of signal arrival based upon the polarization of the signal. Thus, the antenna geometry does not physically change but the processing “teases” out the polarization of the incoming electric and magnetic fields and thus determines the angle of arrival. This is best suited for low frequency applications such as HF.

Session 8 - Smart Adaptive Arrays/Active Electronically Steered Arrays
September 27 - 1300-1600 EDT (1700-2000 UTC)
The most advanced approach to “Smart Antennas” is the full adaptive array that can continuously adapt to ever changing electromagnetic environments. The adaptation is accomplished by using feedback to allow the user to null interferers while simultaneously finding signals of interest. A detailed explanation of the behavior and performance is presented.
