Power and Beauty of Contour-FFT Method for the Rapid and Efficient Analysis of Mutual Coupling in Antenna Arrays
Summary
The mutual coupling plays an important role in the antenna arrays. The radiation pattern of an antenna that is located in an isolated environment is very much different when the same antenna is placed in the array environment due to the mutual coupling effects. Moreover, based on the location of the antenna inside the array (e.g. in the middle, at the edge or located elsewhere), the radiation patterns are very different. For several antenna applications, like massive MIMO communication systems, radar applications, phased arrays, space applications and astronomical applications, it is very much necessary to be able to calculate the embedded element patterns accurately and rapidly such that these patterns can be used in the full analysis of the system design. The antenna arrays are becoming more dense having irregular placements and shapes. Let us consider an example of astronomical applications; where the number of antennas ranges from hundreds to thousands. If these antennas are placed regularly or/and if the shapes are regular, the analysis time can be manageable within a few 10's to few 100's of hours. But if they are placed at the irregular or/and the shapes are irregular, the analysis time can take a few days to arrive at the solutions. This issue has been tackled with a new application of Contour-FFT method, i.e. the application of the FFT to the singular functions which reconciles the application of FFT method with accurate estimation of the mutual coupling effect with NlogN complexity. Basically, the proposed Contour-FFT technique provides an on-the-fly analysis approach. This brings analysis time to 10s of minutes instead of 10s of hours. This talk will focus on what the Contour-FFT concept is? What are the recent applications that it has helped solve? And What are the potential applications it holds to solve?
With this keynote talk, audience will have opportunity to be informed on several other fast methods for the efficient analysis of antenna arrays.
