Xnec2c is a high-performance multi-threaded electromagnetic simulation package to model antenna near- and far-field radiation patterns for Linux and UNIX operating systems.

A rectangular microstrip patch antenna is a type of antenna with a rectangular metallic patch printed on a dielectric substrate. HFSS, or High Frequency Structural Simulator, is a powerful software tool for designing and analyzing such antennas, providing accurate simulations of their electromagnetic performance.
