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 ...
Variation in Bandwidths Among Solutions to Shaped Beam Synthesis Problems Concerning Linear Arrays of Parallel Dipoles
(Institute of Electrical and Electronics Engineers, 2005-01)
The problem of synthesizing a linear array generating a shaped beam pattern with M filled s has 2M alternative solutions. In this study we examined their bandwidths as regards compliance with pattern quality or input ...
Variation in The Bandwidths of Pattern-Quality Parameters and Maximum Embedded Impedance among the Solutions to Shaped-Beam Synthesis Problems for Collinear Dipole Arrays
(Institute of Electrical and Electronics Engineers, 2003)
[Abstract] We investigated variation in the bandwidths of ripple, sidelobe level, -3 dB beamwidth, and maximum element embedded (active) impedance (|Z/sup e/|/sub max/) among multiple collinear dipole arrays radiating a ...
Very Fast Method to Synthesise Conformal Arrays
(The Institution of Engineering and Technology, 2007-08-02)
[Abstract] A very fast technique that allows the synthesising of arbitrary footprint patterns by using conformal arrays with many radiating elements is described. This method is based on a combination of Woodward-Lawson ...
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, ...
New Toroidal Beam Antennas for WLAN Communications
(Institute of Electrical and Electronics Engineers, 2007-02)
[Abstract] The design of a number of new antennas that radiate linearly polarized toroidal beams is described. The developed procedures are based on the use of a method of moments commercial software tool. Several numerical ...
Perturbation of the Phases of Taylor Field Samples in the Synthesis of Linear and Circular Array Antennas
(Institute of Electrical and Electronics Engineers, 2004-12)
[Abstract] Antenna design specifications do not usually restrict the phase of the radiated field. Antenna synthesis techniques generally exploit this freedom only indirectly, but direct phase perturbation can be fruitful.
Synthesis of Multi-Radial Line Antenna for HIPERLAN
(The Institution of Engineering and Technology, 2003-08)
[Abstract] We present a new antenna concept - the multi-radial travelling wave line antenna - that achieves a broadband conical radiation pattern suitable for use in multiple C-band wireless computer networks.
A MATLAB Interface for Analyzing Conformal Arrays Composed of Polarized Heterogeneous Elements
(Institute of Electrical and Electronics Engineers, 2011-10)
[Abstract] As an extension and improvement of a previous work, this paper presents a graphical interface designed with MATLAB®, which is capable of representing both the spatial and electrical configurations of a conformal ...
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 ...
