Design Procedures for Rectangular Patch Antennas

The work presented in this paper aims at comparing different approaches for the design of a rectangular microstrip patch antenna operating at millimeter waves. In the paper, the designed antenna is simulated using approximate formulas available from previous research, and also using the electromagnetic software CST (Computer Simulation Technology). Precisely, two optimization procedures are proposed for the same desired antenna, one using the internal CST optimizer and the other the modeFRONTIER software, which is specifically designed for solving optimization problems. All the obtained results are mutually compared, thus highlighting advantages and drawbacks of these approaches.
