Investigation of mutual coupling coefficients in dual-polarized antenna arrays
Физика волновых процессов и радиотехнические системыBackground. Antenna arrays are widely used in various fields of radio engineering, such as radio and telecommunications, satellite communication systems, etc. One of the important characteristics of an antenna array is its radiation pattern.

Mutual coupling compensation in receiving antenna arrays
2020 International Applied Computational Electromagnetics Society Symposium (ACES), 2020 Mutual coupling compensation in uniform linear and circular receiving antenna arrays of thin wire dipoles is presented. It was observed that the mutual impedance is independent of the incident angle and depends solely on the geometry of the array.

Mutual Coupling Effect of Microstrip Antenna Array
Procedia Engineering, 2012 Microstrip patch antenna is widely used due to the advantages such as small size and mass. However, when the patches are close to each other, the mutual coupling can’t be neglected.

Effects of Reentry Plasma Sheath on Mutual-Coupling Property of Array Antenna [PDF]
International Journal of Antennas and Propagation, 2015 A plasma sheath enveloping a reentry vehicle would cause the failure of on-board antennas, which is an important effect that contributes to the “blackout” problem.

A Metasurface Superstrate for Mutual Coupling Reduction of Large Antenna Arrays [PDF]
IEEE Access, 2020 In this paper, a ε-negative metasurface superstrate is proposed for mutual coupling reduction of large antenna arrays. Unlike the previous decoupling metasurface works that are mostly confined to two-ports antennas, the proposed decoupling ...

Mutual Coupling Effects Analysis in a Cross-Rhombic Antenna Array [PDF]
International Journal of Antennas and Propagation, 2012 We present an analysis of mutual coupling effects on radiation pattern and individual coupling in a conformal array of cross rhombic antennas. Analysis is made using both full-wave simulation and numerical approaches implemented in Matlab.

Mutual coupling effects in linear antenna arrays
Canadian Journal of Physics, 1970 The effects of mutual coupling among the array elements on the pattern and impedance characteristics of linear antenna arrays are examined. Based upon the assumption that the mutual impedance of two array elements depends only upon the separation of the

International Journal of Antennas and Propagation, 2014 In the circular polarization antenna array, the input impedance, axial ratio, and radiation pattern of antenna patch will be changed. Compared with the performances of single antenna, the mutual coupling also led to the low efficiency of all antennas.

Leveraging Mutual Coupling in Antenna-Amplifier Systems for Increased Reconfigurability
IEEE Journal of MicrowavesTraditional antenna array design aims at minimising the mutual coupling between the elements. When elements are fully isolated, the active impedance seen by the amplifiers does not depend on the beam steering angle.
