1. Introduction A microstrip patch antenna consists of a radiating metallic patch printed on a grounded dielectric substrate. It is widely used in wireless communication (Wi-Fi, GPS, 5G, RFID) due to its low profile, light weight, and ease of fabrication. microstrip patch antenna calculator

For a reliable design, combine calculator output with electromagnetic simulation and at least one physical iteration. Happy antenna designing! End of piece. if name == " main ": result = microstrip_patch_calc(2
