Introduction: Electric dipole fields show an increasing contribution to Ultimate Intrinsic SNR (UISNR) at high fields. Substantial SNR boosts have been shown in a body sized phantom at 7.0 T by using a combination of loop and electric dipole elements. A mixture of element types may also improve the performance of parallel transmit array designs, but with most parallel transmit systems currently...

The multiple-input multiple-output (MIMO) performance of the modulated scattering antenna array (MSAA) is analyzed numerically for the first time in indoor environment based on an approach to hybridization of the Volterra series method and method of moments (MoM) in this letter. Mutual coupling effect between the Modulated scattering element (MSE) and the normal antenna element is also consider...

This paper presents an optimum design technique of an asymmetric V-dipole antenna and it’s a three-element Yagi-Uda array using Genetic Algorithm (GA). The optimization parameter for the V-dipole is the directivity and that for the Yagi-Uda array are the input impedance and directivity. The theoretical analysis has been done using a Moment-Method technique in a very simple step-by-step way, and...

We present the numerical parametric study of a reconfigurable plasma antenna array (PAA) composed of a metallic half-wavelength dipole and a set of cylindrical plasma discharges arranged in a planar square lattice. Our results, obtained with the linear embedding via Green’s operators (LEGO) method, indicate that beam-forming and beam-steering functionality can be achieved and controlled by appr...

This paper describes the characteristics of a software developed on MatLab Scripts to obtain the radiation patterns of linear antenna arrays using dipoles as the elements. The software includes, among several other options: the analysis and design of arrays with progressive phase, arrays with non uniform amplitude excitation and arrays with non uniform separation. Some special attributes of the...
