Managing Interference in Antenna Collocation: Innovative Strategies for Enhanced Communication Performance
Antennas play a pivotal role in wireless communication, and as wireless technologies continue to advance, the collocation of diverse antennas with varying polarizations and frequency bands has become a prevalent practice across communication platforms, including base stations, satellites, and various vehicles. This approach optimizes spectrum utilization, bolsters spectral efficiency, minimizes interference, and facilitates multi-band communication. It empowers efficient space utilization, cost-effectiveness, and the adaptability of communication systems to evolving technology and spectrum demands.
However, antenna collocation introduces significant challenges, primarily in the form of substantial mutual interference among antennas. This interference can lead to performance degradation in critical parameters such as antenna matching, isolation, and radiation patterns. Such performance deterioration can have a cascading impact on the overall communication system, affecting its effectiveness and reliability. Consequently, effectively managing and mitigating interference represents a pivotal aspect of successful antenna collocation in complex communication environments.
This talk will introduce three distinct works undertaken in Dr. Can Ding’s group to address these challenges from different angles:
Cross-Band interference: The first work focuses on mitigating interference among dual-band antenna arrays by developing electromagnetically-invisible antenna elements. These elements operate normally in one band while remaining "invisible" in other bands, effectively suppressing interference.
In-Band interference: The second work concurrently tackles three types of couplings between closely-spaced dual-polarized antennas, offering in-band full-duplex solutions within the antenna domain, enhancing spectrum utilization.
Mixing Orthogonal Polarizations: The third work employs a different strategy, harnessing, rather than mitigating, interference between two orthogonally-polarized radiations. This approach equips a dual-polarized antenna array with additional functionalities and significantly reduces costs.
