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.If you have any difficulties with understanding provided concepts and design steps - simply ask me a question!
