Abstract
As wireless communication technologies evolve toward higher frequencies, spectrum above 40 GHz—particularly the Ka-, V-, and W-bands—has emerged as a critical frontier for next-generation satellite and terrestrial systems. Yet, research infrastructure for observing and characterizing these high-frequency signals remains limited on most university campuses. This project aims to establish a receive-only satellite ground station at the University of Notre Dame capable of detecting and measuring the power of high-frequency signals. By beginning with the unlicensed 60 GHz band (WiGig) and extending toward experimental V-band frequencies, the system will provide a platform for spectrum monitoring, propagation studies, and future satellite-link experiments. The semester’s work focuses on three stages: (1) identifying a target frequency band through documentation of current allocations and active transmitters; (2) designing a hardware chain composed of a horn antenna, low-noise amplifier, downconverter, and spectrum analyzer or software-defined radio; and (3) validating performance through controlled terrestrial signal measurements. Once completed, the ground station will serve as a foundation for continued mmWave research and education, enabling students and researchers to explore high-frequency spectrum behavior and support ongoing national efforts in 6G and satellite communications innovation.
