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 ...
A Comparison of Optimization Techniques for Power Patterns with Low Sidelobes Generated by Linear Arrays with Efficient Excitation Distributions
(John Wiley & Sons, Inc., 2005-04-05)
[Abstract] Equispaced linear arrays that have uniformly excited central elements and monotonically decreasing flanking segments have been shown to yield low-sidelobe patterns with specified constraints on the effective ...
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 ...
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.
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 ...
Near-Field Quasi-Null Control with Far-Field Sidelobe Level Maintenance in Line Source Distributions
(The Institution of Engineering and Technology, 2002-06-06)
[Abstract] An improving method, based on the Taylor line source, that allocates a quasi-null in a specified angular position of near-field pattern, and simultaneously controls the general topography of the far-field sidelobe ...
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 ...
Beam Reconfiguration of Linear Arrays Using Parasitic Elements
(The Institution of Engineering and Technology, 2006-02-13)
[Abstrac] An innovative method for linear arrays beam reconfiguration is presented. This pattern reconfigurability is achieved by a mechanical displacement of a parasitic array located in front of an active one. Two worked ...
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.
