摘要:

The famous Friis antenna formula relating received power to transmitted power, distance between antennas, wavelength, and antenna areas is derived in the Fraunhofer approximation utilizing the results of single‐slit diffraction theory. Since the original exact formula was derived from Fresnel theory this Fraunhofer treatment improves its accessibility for undergraduates.
