Compensation of mutual coupling effects in array antennas
IEEE Antennas and Propagation Society International Symposium. 1996 Digest, 2002The possibilities of compensating for the mutual coupling in array antennas are discussed. An alternative method of viewing the matrix multiplication technique used to compensate for these effects is presented. The signals applied to the antenna ports are modified in order to neutralize the mutual coupling effects.

Antenna and diffraction mode decomposition of mutual coupling in antenna arrays
IEEE Antennas and Propagation Society Symposium, 2004., 2004In this paper, an evaluating method of array patterns is presented. This method considers all the mutual coupling effects. It consists in assuming that the field of an element is the sum of two distinct modes: an antenna mode and a diffraction mode. Good results are obtained for a finite linear dipole array.

Frugal calibration of mutual coupling in large scale antenna array
2017 13th International Wireless Communications and Mobile Computing Conference (IWCMC), 2017In a time-division duplexing (TDD) system, the uplink (UL) and downlink (DL) channel reciprocity gets impaired due to the mismatches of the antenna radio frequency (RF) electronics. Meanwhile, in massive multiple-input multiple-output (MIMO), as the antenna elements are placed close to each other, the mutual coupling effects among the adjacent antennas

Mutual Coupling Characteristics of Choke Loaded Patch Array Antenna
IEICE Transactions on Communications, 2005This paper describes the choke-loaded patch array antenna for use in the IMT-2000 repeater systems. The choke structure of the 4-element array is designed by means of an electromagnetic analysis. A high front-to-back (FB) ratio is required for suppressing mutual coupling in order to stop the oscillation caused by the interference waves between a ...

Mutual coupling effects in linear antenna arrays
Canadian Journal of Physics, 1970The 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 elements, exact expressions are derived for the properties of infinite and semi-infinite arrays ...

Mutual Coupling Enhancement in Antenna Array
Антенные решетки очень важны в беспроводных сетях связи, так как они могут выдерживать изменение направления излучения, при этом требуется высокая пропускная способность и высокий коэффициент усиления. Взаимная связь (МС) между антенными решетками влияет на некоторые параметры, импеданс, коэффициенты отражения, поперечное сечение радара и ...Sirwan Kareem Jalal, Peshawa O. Amin
