CONCLUSION A judicious approach to the EM simulation of antenna arrays is represented in the incremental analysis structure; starting with a complete exploration of a single element of the array, and subsequently advancing to additional elements of the rows and columns. The investment of an incremental structure yields benefits in the form of reduced EM analysis time and improved correlation between expected and achievable performance – not to mention reducing the inherent anticipatory stress during simulation execution time. The discussion related to microstrip antenna feed has been limited to that of the direct feed at the conductor edge, which results in limited operational bandwidth. The operational bandwidth of microstrip antennas may be significantly increased via implementation of an aperture coupling below the microstrip element; the improved performance is accompanied by the additional complexity and cost of a dielectric and conductor layer below the radiating elements.
