Compact Three-Port Antenna Diversity Systems for Low Probability of Detection Communication

Ensuring the security of data transmitted over wireless links is a critical concern across civilian and military applications. In contemporary times, the protection of data in wireless networks against interception by adversaries is commonly achieved through diverse cryptographic methods. Despite these efforts, conventional cryptographic security often falls short, particularly when facing intelligent adversaries who possess in-depth knowledge of the systems and techniques in use. In such circumstances, the necessity for low probability of detection (LPD) communication arises to prevent the initial detection of transmissions.
