The modeling of a radiated printed structure

This paper reports on the simulation technique based on the high frequency structure simulator HP HFSS 5.5 used to calculate a three-dimensional radiated printed structure. The four elements microstrip antenna with feeding line was proposed as such structure. During the past 25 years the microstrip antennas were intensively developed due to their low profile, lightweight features, low cost and simplicity of manufacture. The patches of various forms can be used as radiated elements, (for instance, they may be rectangles, triangles, squares, disks, rings) to design antennas with linear or circle polarization. There are many methods of the microstrip antennas calculation but for complex configurations of the radiated structure it´s difficult to present the completeness of electromagnetic processes inside a structure and exclude or minimize tuning elements. The high frequency simulation allows accelerating of manufactory process; for instance, an antenna topology drawing may be used for the template producing.
