Mutual Coupling Effect of Microstrip Antenna Array [PDF]

Procedia Engineering, 2012
AbstractMicrostrip 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. So RWG (Rao-Wilton-Glisson) and Method of Moments are chosen as the basic algorithm, then the mutual coupling can be visualized by the means of mutual impedance ...

Investigation of mutual coupling coefficients in dual-polarized antenna arrays

Физика волновых процессов и радиотехнические системы
Background. 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 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.

Direction-of-Arrival Estimation of Electromagnetic Wave Impinging on Spherical Antenna Array in the Presence of Mutual Coupling Using a Multiple Signal Classification Method

Electronics, 2021
A spherical antenna array (SAA) is the configuration of choice in obtaining an antenna array with isotropic characteristics. An SAA has the capacity to receive an electromagnetic wave (EM) with equal intensity irrespective of the direction-of-arrival ...

Synthesis of Antenna Arrays and Parasitic Antenna Arrays with Mutual Couplings [PDF]

International Journal of Antennas and Propagation, 2012
A synthesis method to design multielement antennas with couplings is presented. The main objective is to perform a rigorous determination of the electromagnetic characteristics involved in the design, especially with arrays of moderate sizes. The aim is to conceive jointly and efficiently the antenna and the circuits to connect (feed distribution ...

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. By using only one measurement, decoupling matrix is computed and direction of arrival is estimated.
