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 in Antenna Arrays 2013
International Journal of Antennas and Propagation, 2014 The invention of antenna arrays opened up the door for microwave sensing and communications. Most applications of antenna arrays are in the defense and wireless communications areas. The introduction of multiple-input-multiple-output (MIMO) concept in recent years has opened up further opportunities in that the system performance can be maintained with

Compensation for the mutual coupling in transmitting antenna arrays
2016 IEEE Asia-Pacific Conference on Applied Electromagnetics (APACE), 2016 A numerical study is presented for the compensation of mutual coupling in antenna arrays. A Matlab code based on method of moments is used to find the compensated far field radiation patterns for non-identical and/or staggered wire antenna arrays. The isolated patterns for some antenna arrays when applicable are found using the principle of pattern ...

Mutual coupling compensation in small array antennas [PDF]
IEEE Transactions on Antennas and Propagation, 1990 A technique to compensate for mutual coupling in a small array is developed and experimentally verified. Mathematically, the compensation consists of a matrix multiplication performed on the received-signal vector. This, in effect, restores the signals as received by the isolated elements in the absence of mutual coupling.
