Visualizing radiation patterns of antennas
IEEE Computer Graphics and Applications, 1990An efficient computer graphics tool for investigating the radiation patterns of antennas as functions of their design parameters is presented. Radiation patterns (or the magnitudes of field distributions) of antennas are treated as three-dimensional surfaces, since the magnitudes of the far-field distributions are functions of polar and azimuthal ...

Antenna Radiation Pattern Compressive Sensing
MILCOM 2018 - 2018 IEEE Military Communications Conference (MILCOM), 2018Modern wireless communications is placing ever greater demands on the system's antenna. But high-resolution, wide-band antenna pattern measurement remains a slow, expensive process that can hinder research, development, and production. This paper explores the use of compressive sensing to accelerate the measurement process.

Radiation Pattern Reconfigurable Horn Antenna
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019A radiation pattern reconfigurable horn antenna (RHA) capable of steering its main beam in three directions in the semi-sphere space corresponding to θ ∈ {−25°, 0°, 25°}, is presented. The RHA consists of a driven X-band (10 GHz-11.5 GHz) horn antenna, a reconfigurable parasitic layer and a dielectric loaded truncated pyramid (DLTP). The surface of the

Radiation patterns from lens-coupled terahertz antennas
Optics Letters, 1995We report on investigations of the angular distribution of the radiation emitted from a terahertz antenna system equipped with a truncated spherical silicon lens. The pattern is calculated by wide-angle interference principles and Huygens-Fresnel diffraction theory.

Plasma Antenna Radiation Patterns
AIP Conference Proceedings, 2003Elevation angle pattern measurements of our Plasma Antenna are presented and compared with results from computer models. Good agreement is found for the measurements with patterns predicted by our linearly decreasing conductivity model for the plasma antenna, derived from computer models using readily available packages.

Radiation pattern of cylindrical‐wraparound chirostrip antennas
Microwave and Optical Technology Letters, 1999In this paper, a cylindrical-wraparound microstrip antenna flush mounted to the upper surface of a chiral substrate is analyzed. The chiral substrate is wrap fabricated around a conducting core cylinder. Dyadic Green's functions for such a cylindrical structure are formulated in terms of cylindrical vector wave eigenfunctions.

A reconfigurable radiation pattern metamaterial-inspired antenna
2014 Loughborough Antennas and Propagation Conference (LAPC), 2014In this work, a reconfigurable radiation pattern metamaterial-inspired antenna is proposed. The structure consists of simple split resonator (SRR) loaded with two open circuits and introduced into the near field region of a monopole antenna. Two configurations are studied by considering the state of the open circuits.

Calculating antenna radiation patterns
Electrical Engineering, 1944CALCULATIONS of the horizontal relative field patterns of antennas are long and laborious and increase in complexity with the number of antenna elements employed. Present calculating machines are useful only for antenna-beam arrays consisting of not over three elements.

Simulation of antenna radiation pattern
Microwave and Optical Technology Letters, 1995AbstractAdequately modeling the radiation pattern of a high‐performance antenna system usually requires the expensive development of complicated electromagnetic software or the storage of an extremely large number of measured data. An alternative and efficient simulation technique is described in this article using a spherical wave expansion model ...
