This study examines how receivers can be degraded by nearby transmitters, in terms of distance and frequency, due to antenna coupling on large electrical structures. The objective is to identify methods for antenna placement to prevent self-generated interference in environments where transmitters and receivers coexist, using a communications satellite’s Telemetry, Command, and Ranging (TCR) in the Ka-Band as a case study. This analysis develops a systematic approach that uses conventional computers to achieve reliable simulation within reasonable times. The work includes simulations using CST Studio Suite software, theoretical approximations, and validation through measurements to achieve the technical challenges effectively.
