A Compensation Method for the Array Antennas Mutual Coupling
2020 Cross Strait Radio Science & Wireless Technology Conference (CSRSWTC), 2020A method of mutual coupling compensation for array antenna based on measured patterns is studied. By analyzing the coupling matrix, the conjugate gradient method is used to fit the two sets of pattern data. Estimate the coupling matrix and perform weighted coefficient compensation to minimize the effect of mutual coupling on the sidelobe level.

Mutual Coupling Reduction of Slot Antenna Array by Controlling Surface Wave Propagation
IEEE Transactions on Antennas and Propagation, 2019In this communication, we present a methodology to reduce mutual coupling in a planar slot antenna array by using electric metamaterial. The proposed methodology is based on resisting and steering the propagation of surface wave.

Surface-Wave Control Technique for Mutual Coupling Mitigation in Array Antenna
IEEE Microwave and Wireless Components Letters, 2022We propose and investigate an easy technique to mitigate the mutual coupling of integrated antenna elements caused by surface waves in a high-permittivity grounded dielectric substrate, which can be deployed for high-density integration of antenna and ...

Mutual coupling in monopole phased array antennas
1984 Antennas and Propagation Society International Symposium, 2005An experimental and theoretical study of the mutual coupling in large periodic planar phased arrays of cylindrical monopoles is addressed. Results are given for the passively terminated array coupling coefficients from which the active array scan impedance is computed. Element gain patterns are also presented.

FSS and Meta-material Based Low Mutual Coupling MIMO Antenna Array
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019A multi-layers frequency selective surface (FSS) with meta-material is presented for reducing the mutual coupling in a MIMO antenna array, where the FSS elements are realized by using the periodic split ring resonators (SSRs).

Microwave and optical technology letters (Print), 2019
This paper presents a novel slotted wideband microstrip patch antenna array with 2 decoupling structures that enabled isolation enhancement between 10 and 40 dB throughout the operating bandwidth of 4‐6.5 GHz. Four asymmetrical patches were first used as

Mutual Coupling Effects in Thinned Antenna Arrays
1974 4th European Microwave Conference, 1974The reduction of mutual coupling effects is one interesting advantage of thinned antennas for phased array systems. This paper deals with the reflection coefficients and the antenna gain both as functions of the degree of thinning in statistically highly-thinned arrays. Appropriate statistics are derived, discussed, and experimentally tested.
