Mutual coupling effects on adaptive antenna arrays
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990The authors examine the effects of mutual coupling on an adaptive array system and propose the use of scalar spherical modes (SSMs) to predict and correct the problem. Preliminary results are presented: the receive patterns of an ideal ten-element half-wave dipole array and a ten-element half-wave dipole array with mutual coupling are shown.

Tacking mutual coupling in antenna arrays for wireless communications
International Conference on Advanced Infocomm Technology 2011 (ICAIT 2011), 2011A new model for tacking mutual coupling in wireless communications is introduced. A new concept of receiving mutual impedance is introduced and explained theoretically. Receiving mutual impedances for typical antenna arrays are obtained. Application of the new method is demonstrated in several arrays for direction finding, adaptive nulling, and MIMO ...

Compensation of mutual coupling in small antenna arrays
14th International Conference on Microwaves, Radar and Wireless Communications. MIKON - 2002. Conference Proceedings (IEEE Cat.No.02EX562), 2003Far-field pattern synthesis of small antenna arrays is a nontrivial problem, mainly due to mutual coupling, often precluding the use of conventional tapering algorithms. A technique to compensate for mutual coupling in small linear antenna arrays is described. The method consist of calculations of a coupling matrix, which is then used to compensate for

Mutual coupling reduction in patch antenna arrays
2018 IEEE International Vacuum Electronics Conference (IVEC), 2018In this paper, meander line (ML) as a parasitic configuration is introduced to reduce the mutual coupling (MC) between two microstrip patch antenna elements. Inserting a slot in the middle of ground plane is a simple method to reduce the MC, by adding the ML in the proper position in the slot can further reduce the MC.

Mutual coupling compensation of array antenna pattern
2015 IEEE International Conference on Communication Software and Networks (ICCSN), 2015In order to analyze the impedance characteristics intuitively, the array antenna is equivalent to a port network. Based on this model, the relation between mutual coupling and mutual impedance is obtained, and a way to modify pattern considering mutual coupling is introduced.

Mutual Coupling Compensation in Receive-Mode Antenna Array Based on Characteristic Mode Analysis
IEEE Transactions on Antennas and Propagation, 2018In this communication, the characteristic mode analysis (CMA) is applied to the analysis of mutual coupling in a receive-mode antenna array with geometric symmetry.

Effects of mutual coupling in smart antenna arrays
2007 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference, 2007The radiation pattern in the H-plane of smart antenna arrays (SAA), which includes the effects of mutual coupling (MC) is examined. In an SAA the effects of MC and nonuniform spacing between the array elements are compensated with the use of a transformation matrix T.

On the Mutual Coupling of the Finite Microstrip Antenna Arrays
2007 International Symposium on Electromagnetic Compatibility, 2007Mutual coupling between radiation frequency (RF) components, antenna elements in a microstrip antenna array or between two microstrip antenna arrays is a potential source of the performance degradation. The degradation includes the impedance mismatching, the increased side-lobe level, the deviation of the radiation pattern from the desired one, and the

Mutual coupling in microstrip antenna array elements
2006 First European Conference on Antennas and Propagation, 2006The mutual coupling between adaptive antenna array elements degrades the performance of the array especially for direction finding purpose. There are many possible ways to compensate the coupling effects via electromagnetic analysis or via signal processing. We are going to follow the first approach to determine the mutual coupling and we are following
