On the Multiplicity of Solutions of Taylor Linear Sources Generating Symmetrical Power Patterns with Filled Nulls
(Institute of Electrical and Electronics Engineers, 2004-12)
[Abstract] As expressed in earlier works, if filled nulls are required in a power pattern generated by a Taylor line source, their corresponding roots must be complex. This leads to a multiplicity of solutions emerged from ...
Optimizing Uniformly Excited Linear Arrays through Time Modulation
(Institute of Electrical and Electronics Engineers, 2004-12)
[Abstract] The letter shows that, by the proper use of time modulation in equispaced linear arrays with uniform excitation distribution, it is possible to maintain the sidelobe zone of the radiated power below a certain - ...
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.
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 ...
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 ...
