    Propagation models are used to abstract the actual propagation characteristics of electromagnetic waves utilized for conveying information in a compact form (i.e., a model with a small number of parameters). The correct modeling of propagation and path loss is of paramount importance in wireless sensor network (WSN) system design and analysis [1]. Most of the important performance metrics commonly...

  • A Step Toward 5G in 2020: Low-cost OTA performance evaluation of massive MIMO base stations.

    Publication Year: 2017, Page(s):38 - 47
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (4504 KB) | HTML iconHTML

    Massive multiple-input, multiple-output (MIMO) is seen as an enabling technology to fulfill dramatic improvements in spectral efficiency for fifth-generation (5G) deployment in 2020. For massive MIMO systems, the learning loop from early-stage prototype design to final-stage performance validation is expected to be slow and ineffective. There is a strong need to evaluate massive MIMO base station ... View full abstract»

  • Optimization of a Printed UWB Antenna: Application of the invasive weed optimization algorithm in antenna design.

    Publication Year: 2017, Page(s):48 - 57
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3638 KB) | HTML iconHTML

    This article presents a general approach to design and optimize printed ultrawideband (UWB) antennas by using invasive weed optimization (IWO), a well-known global optimization algorithm. To achieve the required radiation parameters over a wide bandwidth, a frequency-related cost function with optimal weighting coefficients is suggested. Two prototypes of the optimized antenna have been manufactur... View full abstract»

  • Weathering Sand and Dust Storms: Particle shapes, storm height, and elevation angle sensitivity for microwave propagation in earth-satellite links.

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (3776 KB) | HTML iconHTML

    Microwave propagation characteristics in earth-satellite links during sand and dust storms are sensitive to the shape of particles, the height of such storms, and the elevation angle. In this article, the formulas of total attenuation and phase shift in earth-satellite links for spherical sand and dust particles are developed in terms of visibility, frequency, elevation angle, and height. Obtained... View full abstract»

  • Refining Transient Electromagnetic Scattering Analysis: A new approach based on the magnetic field integral equation.

    Publication Year: 2017, Page(s):66 - 73
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (11133 KB) | HTML iconHTML

    The magnetic field integral equation (MFIE) in a time-domain form is used to describe transient electromagnetic (EM) scattering by conductors. The MFIE is a second kind of integral equation that can help improve the conditioning of the matrix equation but is less widely addressed in the time domain. The time-domain MFIE (TDMFIE) is generally solved by the spatial-domain method of moments (MoM) at ... View full abstract»

  • Antenna Design Using Binary Differential Evolution: Application to discrete-valued design problems.

    Publication Year: 2017, Page(s):74 - 93
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (5764 KB) | HTML iconHTML

    Several antenna design problems are discrete valued. Particle swarm optimization (PSO) and differential evolution (DE) are popular evolutionary algorithms that have been applied to a number of design problems in electromagnetics. However, both PSO and DE are best suited for continuous search spaces. Therefore, to apply these to binary-coded combinatorial optimization problems, binary versions of t... View full abstract»

    This article reports on the design and development of a novel sharedaperture antenna that is set at the widely separated L5 and S bands for navigation satellite systems with its concentric phase centers located at the two bands. The design of the radiating element and its performance is also detailed as well as the design of the critical sections, namely, the square-coaxialline and waveguide feed ... View full abstract»
