A MATLAB Tool for Visualizing the 3D Polar Power Patterns and Excitations of Conformal Arrays
(Institute of Electrical and Electronics Engineers, 2010-08)
[Abstract] This paper describes the implementation of a MATLAB® tool to plot the three-dimensional polar radiation diagram generated by a conformal antenna array. A related tool has also been developed for visualizing the ...
Calculating Directivities with the Two-Dimensional Simpson's Rule
(Institute of Electrical and Electronics Engineers, 2004-08)
[Abstract] C++ routines implementing the simple generalization of Simpson's rule to two dimensions for calculating antenna directivities compare well with methods currently available in common symbolic and numerical ...
A WiMAX Conformal Broad-Beam Antenna
(Institute of Electrical and Electronics Engineers, 2010-12)
[Abstract] The numerical model of a very simple conformal antenna, prepared to work in the 3.4 to 3.6 GHz WiMAX range, is presented. The pattern radiated by the proposed antenna displays high gain and excellent linear ...
Visualizing the 3D Polar Power Patterns and Excitations of Planar Arrays with Matlab
(Institute of Electrical and Electronics Engineers, 2004-04)
[Abstrac] This paper discusses the use of Matlab to create three-dimensional polar plots of the power patterns of planar arrays together with 3D plots of the amplitudes and phases of their excitations. A few lines of Matlab ...
Near Field Quasi-Null Control with Far Field Sidelobe Level Maintenance in Line Source Difference Patterns
(Taylor & Francis, 2003)
[Abstract] A previously developed method to place a quasi-null in a specified angular position of the near-field line source in sum patterns while, simultaneously, the far-field sidelobe level is maintained under a desired ...
Measurement Effects on Ø-Symmetric Shaped Patterns Generated by Circular Continuous Apertures
(Institute of Electrical and Electronics Engineers, 2003-10)
[Abstract] Sidelobe-level and ripple behaviors of Ø-symmetric shaped patterns, generated by circular, real and complex, continuous Taylor distributions, is analyzed as a function of measurement distances. This paper reveals ...
Effects of Measurement Distance on Measurements of Symmetrically Shaped Patterns Generated by Line Sources
(Institute of Electrical and Electronics Engineers, 2003-02)
[Abstract] Symmetrically shaped patterns, generated by real continuous linear apertures derived from Taylor distributions, resemble Taylor sum patterns in regard to the distance-dependence of their sidelobe heights. Their ...
On the Feasibility of Time-Modulated Arrays for Digital Linear Modulations: a Theoretical Analysis
(Institute of Electrical and Electronics Engineers, 2014)
[Abstract] Wireless communications are widely based on linear digital modulation methods, which introduce the digital baseband information in the amplitude and/or in the phase of a carrier sinusoid. Time-modulated arrays, ...
Enhanced Time-Modulated Arrays for Harmonic Beamforming
(Institute of Electrical and Electronics Engineers, 2017)
[Abstract]: One of the primary features of time-modulated arrays (TMAs) is their ability to adapt their harmonic patterns to exploit the angular diversity of multipath wireless channels. In such a case, the TMA excitations ...
