Mutual coupling effects on antenna radiation pattern: An experimental study applied to interferometric radiometers

Experimental study of mutual coupling compensation in smart antenna applications

This paper investigates the benefit of mutual coupling compensation via a method of moments (MoM) approach in a uniform circular antenna array operating at 1.8 GHz. This mutual coupling compensation technique is applied to a direction of arrival (DOA) study of up to two cochannel mobile users. Field measurements and computer simulations are examined to explore the assumptions of the technique a...

Mutual coupling effects on the capacity of multielement antenna systems

A study of the capacity of multiple element antenna systems is presented, with particular emphasis on the effect that mutual coupling between the antenna elements has on the capacity. The results presented here shows, contrary to some earlier claims, that correlation between different channel coefficients as a function of antenna spacing, can in fact decrease when the mutual coupling effect is ...

Radiation pattern of an UWB wearable antenna: a preliminary study

Performance Analysis of Antenna Array Beamformers with Mutual Coupling Effects

Antenna array beamformers suffer from performance deterioration in the presence of mutual coupling (MC) between array sensors. In this paper, we present a theoretical analysis in terms of the output signal-to-interference-plus-noise ratio (SINR) for the performance of antenna array beamformers under MC effects. Based on the model of a distortion matrix to encapsulate the MC effects, a closed-fo...

Design of Planar Microstrip Antenna Arrays and Mutual Coupling Effects

In patch antennas, characteristics such as high gain, beam scanning, or steering capability are possible only when discrete patch elements are combined to form arrays. The elements of an array may be spatially distributed to form a linear, planar, or volume array. Planar arrays have elements distributed on a plane. Planar array configurations are extensively used in both communication and radar...
