At the time of writing this post, I was not aware of the following tools which also deal with phased array antenna design: This project is still under construction like all my other projects ? P.S. So, I decided to create a GUI program based on MATLAB which can answer at least some of the very important issues related my favorite topic.

But, a devoted tool providing all possible solutions for antenna arrays is not available at this moment. Yes, we do have CAD tools such as HFSS, CST, ADS, etc and they are very helpful for a microwave engineer. However, we don’t have proper tools to educate students (or engineers) on this topic. So, as the number of array elements increases, we need to use computer for all those numerical calculations. However, human brains have their limitations.

As a matter of fact, those manual computations give us very interesting insight into concepts such as grating lobes, side-lobe level, etc. I am not saying that those calculations were useless. But unfortunately to analyze even a very simple array, I had to do cumbersome array factor evaluations to finding pattern nulls, gain, etc. But one thing that really attracted me was the concept of analysis and synthesis of antenna arrays. Though the theory provided on antenna arrays in that book is not of advanced level, it gave me an insight into this beautiful world of imaginary electromagnetic waves trying to co-ordinate (interfere) with each other so that they can fulfill their assigned jobs (like scanning or adjusting side lobes, etc). The book was Electromagnetic Waves And Radiating Systems. It introduced me to a wonderful world of radiation, fields, antennas and so many other things. Regarding my previous project (MATLAB version of the “Arraytool”, which is not open source) When I was an undergraduate, I had this wonderful opportunity to study a book by “E.

In my opinion, Ludwig-3 definition is still a good compromise among various available polarization definitions. The zero-phase Dolph–Chebyshev window function w0(n) is usually defined in terms of its real-valued discrete Fourier transform. Such a window is generated by the MATLAB function hann(512,'periodic') for instance. In signal processing, a window function is a mathematical function that is zero-valued outside of.

(Last revision: ) These two articles are meant to understand the concept of polarization more clearly.
