Mutual coupling compensation in small phased array antennas
IEEE Antennas and Propagation Society Symposium, 2004., 2004A new technique to compensate for the mutual coupling effect in small phased array antennas is presented. This method is a modification to the classical approach for correcting the array output vector by multiplication of a decoupling matrix to achieve a less unperturbed array response. Two different methods of calculating coupling coefficients between

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.

Planar Phased-Array Antennas: Mutual Coupling and Ultralow Peak Sidelobes
IEEE Antennas and Propagation Magazine, 2019This article will deal with the impact of mutual coupling on the far-field peak sidelobe performance of a finite planar phased-array antenna having a circular aperture shape and containing 2,066 elements arranged in a triangular grid. The radiator that is used is of the open-ended rectangular waveguide type, vertically polarized. The computation of the

Mutual coupling effects in wideband microstrip antenna arrays
2003The paper presents theoretical and experimental investigations of mutual coupling between stacked microstrip patch antennas. The numerical modeling of mutual coupling between stacked patch antennas is developed by solving the electric field integral equation (EFIE) in spectral domain using two-dimensional Fourier transform.

Correction of mutual coupling in digital antenna array
Proceedings of International Conference on Antenna Theory and Techniques, 1995Attempting to realize all potential features of antenna array frequently faces technological problems. One of the possible ways of lowering the influence of technological inaccuracies of digital antenna arrays (DAA) manufacturing is the application of the correction of the receiving channels performance based on the test-signals.In this report, a ...
