More details

Description
Simple step-by-step instructions will help you to design antenna arrays with series feeding and parallel feeding networks. You will learn how to "read" electromagnetic field distribution results; you will find out how to calculate radiation pattern and beamforming angle using simple formulas. Moreover, this course includes short introduction to common antenna array configurations that are often used in real radars and communication systems. At the end of this course, you will find practical instructions on slotted waveguide array design and metamaterial antenna design. It's time to replace patch elements with something more robust and wideband. Extremely compact, distilled, with multiple antenna simulation examples using openEMS - a free electromagnetic field solver.
First three lessons - the basics!
In lesson 1 you will learn how to design series-fed arrays with uniform power distribution. Full procedure and simulation example for weighted series arrays available in lesson 6. Lesson 2 shows how to design shunt-fed patch arrays. Lesson 3 reuses inset-fed patch element from lesson 2 to build a parallel-fed antenna array.
Each simulation includes electromagnetic field distribution graph, which is explained in lesson 4.
Lessons 5 and 7 explain radiation pattern and beamforming. These two lessons share common formulas and concepts, such as wavefront. Lesson 6 in-between describes antenna element weighting technique that can be used to reduce side lobe levels at the cost of increased beamwidth.
From the Lesson 8 you will learn how to solve some of the challenges you may face during array design process.
Lesson 9 is a brief introduction to common antenna array configurations.
Additionally, lessons 10 and 11 provide design steps required for slotted waveguide and simple metamaterial antenna design.
This course includes unique example scripts to perform openEMS simulations for all common array antenna configurations (in-line series, shunt-fed and parallel feeding) with routines that output beautiful EM field distribution graphs directly using Octave. No need to export data to other software!
While running openEMS simulations feels a little difficult compared to HFSS or CST Microwave Studio, openEMS is absolutely free, open source and has an active GitHub discussion forum.
If you have any difficulties with understanding provided concepts and design steps - simply ask me a question! I'll try my best to update this course with answers to all your questions on antenna design!
Who this course is for:
Engineers who need simple practical instructions on how to design array antennas
Students who need more practical examples to back up their theoretical knowledge and remove any doubts
Researchers and Educators who need some starting point to do their work faster

Instructor's Courses

I am a research and development engineer with great experience in electronic engineering, microwave design and digital signal processing. I started to create simple computer programs in middle school using QBasic and Turbo Pascal. I've spent significant time learning computer graphics algorithms and game creation using Delphi and OpenGL during my years at university. This hobby was a great motivation for learning linear algebra and analytic geometry.Shortly afterwards, I moved from Delphi to CodeBlocks to program algorithms in C and ease the process of reusing these routines on STM32 microcontrollers. Currently, I research the ways to achieving outstanding performance using existing sensor technologies by implementing better algorithms and designing power-efficient hardware. My software and hardware designs are robust, reliable and easy to use. I hope you will sense it through my courses!
