Total Active Reflection Coefficient: The Total Active Reflection Coefficient (TARC) is a measure of how much power is reflected back into the antenna system when signals encounter impedance mismatches, such as at the interface between the antenna and the transmission line. Minimizing TARC is important to maximize the efficiency of the antenna system.
MIMO (Multiple Input Multiple Output) antennas are commonly used in wireless communication systems to improve the performance and capacity of wireless channels. The characteristics you mentioned, such as mean effective gain, diversity gain, channel capacity loss, envelope correlation coefficients, and Total Active Reflection Coefficient, are important parameters that describe the performance of MIMO systems. Here's an explanation of low and high values for each of these parameters:
Mean Effective Gain:
Low Value: A low mean effective gain indicates that the MIMO system's antennas are not effectively capturing and transmitting signals. This can be due to factors like interference, weak signal strength, or poor antenna design.
High Value: A high mean effective gain suggests that the MIMO antennas are effectively capturing and transmitting signals, resulting in better signal quality and improved system performance.
Diversity Gain:
Low Value: Low diversity gain implies that the MIMO system is not benefiting much from spatial diversity, which means that it may not be effectively combating fading and multipath effects.
High Value: High diversity gain indicates that the MIMO system is effectively using spatial diversity to combat fading and multipath effects, resulting in improved reliability and performance in challenging radio environments.
Channel Capacity Loss:
Low Value: A low channel capacity loss indicates that the MIMO system can efficiently utilize the available channel capacity. There is minimal loss in channel capacity due to factors like interference or signal degradation.
High Value: High channel capacity loss means that the MIMO system is experiencing significant degradation in channel capacity, which can be caused by factors such as interference or poor signal quality. This leads to reduced data rates and system performance.
Envelope Correlation Coefficient:
Low Value: A low envelope correlation coefficient implies that the MIMO antennas are relatively uncorrelated in terms of their signal amplitudes. This is desirable in MIMO systems, as it enhances the spatial diversity gain.
High Value: A high envelope correlation coefficient suggests that the MIMO antennas are strongly correlated in terms of their signal amplitudes. This can result in reduced spatial diversity gain and may limit the system's ability to combat fading and interference effectively.
Total Active Reflection Coefficient:
Low Value: A low total active reflection coefficient indicates that the MIMO antennas have low reflection and efficiently transmit signals. There is minimal signal loss due to reflections or impedance mismatches.
High Value: A high total active reflection coefficient suggests that the MIMO antennas experience significant reflections or impedance mismatches, leading to signal losses and reduced overall system performance.
In summary, low values for mean effective gain, channel capacity loss, envelope correlation coefficient, and total active reflection coefficient are generally desirable in MIMO systems, as they indicate better performance and efficiency. On the other hand, high values for diversity gain are desirable, as they indicate that the MIMO system effectively utilizes spatial diversity to combat channel impairments. The specific acceptable ranges for these parameters may vary depending on the application and system requirements.
