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 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).īut unfortunately to analyze even a very simple array, I had to do cumbersome array factor evaluations to finding pattern nulls, gain, etc. It introduced me to a wonderful world of radiation, fields, antennas and so many other things. The book was Electromagnetic Waves And Radiating Systems. When I was an undergraduate, I had this wonderful opportunity to study a book by “E. Regarding my previous project (MATLAB version of the “Arraytool”, which is not open source)
