A study of mutual coupling as an alternative feed method in phased array antennas
The use of phased array antennas in present day technology is limited, primarily due to the extremely high cost of implementation. This cost is contributed to the expense of phase shifters, which are the traditional method of beam steering in phased arrays. The need to alleviate this cost and avail the technology for commercial use necessitates study into alternative mechanisms for accomplishing beam steering. To this effect, this research is an exploration of one such mechanism. To characterize mutual coupling between microstrip patch antennas and explore its practicality as a feed mechanism, it is necessary to understand the factors controlling the phenomenon. A parametric study of the spacing between patch antennas and the consequent coupling is presented, the results of which are discussed in detail. further study into bandwidth extension and steer controlling techniques are also shown, with discussion on the practicality and future of the mechanism as a candidate for widespread application.
