Journal ArticleDOI
Higher order hierarchical Legendre basis functions for electromagnetic modeling
TL;DR: A new hierarchical basis of arbitrary order for integral equations solved with the method of moments derived from orthogonal Legendre polynomials which are modified to impose continuity of vector quantities between neighboring elements while maintaining most of their desirable features is presented.
Journal ArticleDOI
A Review of the Scattering-Parameter Extraction Method with Clarification of Ambiguity Issues in Relation to Metamaterial Homogenization
Samel Arslanagic,Troels V. Hansen,Niels Asger Mortensen,A. H. Gregersen,Ole Sigmund,Richard W. Ziolkowski,Olav Breinbjerg +6 more
TL;DR: The scattering-parameter extraction method of metamaterial homogenization is reviewed to show that the only ambiguity is that related to the choice of the branch of the complex logarithmic function (or the complex inverse cosine function).
Journal ArticleDOI
An FSS-Backed 20/30 GHz Circularly Polarized Reflectarray for a Shared Aperture L- and Ka-Band Satellite Communication Antenna
TL;DR: In this article, a shared aperture antenna for simultaneous operation at L- (1525 to 1661 MHz) and Ka-band (19.7 to 20.2 GHz and 29.5 to 30.0 GHz) is demonstrated.
Journal ArticleDOI
Direct Optimization of Printed Reflectarrays for Contoured Beam Satellite Antenna Applications
TL;DR: Several contoured beam reflectarrays, that radiate a high-gain beam on a European coverage, have been designed and compared to similar designs obtained using the phase-only optimization technique, showing that the designs obtained are superior in performance, both for multi-frequency and dual-polarization designs.
Journal ArticleDOI
Theory and Practice of the FFT/Matrix Inversion Technique for Probe-Corrected Spherical Near-Field Antenna Measurements With High-Order Probes
TL;DR: In this article, a complete antenna pattern characterization procedure for spherical near-field antenna measurements employing a high-order probe and a full probe correction is described, which allows an arbitrary antenna to be used as a probe.
