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 ...

A Note on the Mutual-Coupling Problems in Transmitting and Receiving Antenna Arrays
IEEE Antennas and Propagation Magazine, 2009In antenna arrays, mutual coupling between antenna elements is well known as an undesired effect, which degrades the performance of array signal-processing algorithms. The compensation of such an undesired effect has been a popular research topic throughout the years. Various approaches for mutual-coupling compensation have been developed, and they can

Mutual coupling compensation in narrowband small linear‐antenna arrays
Microwave and Optical Technology Letters, 2004AbstractThis paper presents least squares (LS) and total least squares (TLS) method solutions to compensate mutual coupling effects in a small linear antenna array operating over a narrow frequency band. The validity of the two methods is verified by experimental results performed on a six‐element microstrip patch array operating in the 2.4‐GHz band ...

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
