Noise characterization of a multi-channel receiver using a small antenna array with full diversity for robust satellite navigation

The employment of a DMN in small antenna arrays results in an increased antenna noise temperature due to increased ohmic losses. On the other hand, it minimizes the amplifier noise contribution considerably, thus reducing the equivalent system noise temperature. Therefore, the use of a DMN for small antenna arrays displaying full diversity is not only beneficial but necessary for optimizing receiver performance. The analysis sketched here will be extended to null-steering or interferer-cancellation scenarios.
