ANTENNA DECOUPLING
Antenna decoupling is a set of techniques, based on physical and technical mechanisms, used to minimize interference between multiple antennas in an RF system. This ensures optimum performance in terms of radiation and reception, while preserving signal integrity. In modern environments, effective decoupling is essential to maximize the performance of communication systems.
how it works
Antennas can be characterized by several criterias indicating the impact of their coupling:
- Impedance matching, which determines their radiation frequencies.
- Radiation pattern shows how energy is transmitted/received in different directions, enabling analysis of how the antenna radiates or picks up RF signals;
The coupling between antennas can have a significant impact on their resonant frequency. This can lead to a shift outside the frequency band originally intended, and cause distortion of the radiation pattern.
USE CASES
Multi-antenna communication systems
Reduction of interference between MIMO antennas to improve throughput and signal quality in wireless communication systems requiring multiple antennas
