The evaluation of MFIE integrals with the use of vector triangle basis functions
R. E. Hodges,Yahya Rahmat-Samii +1 more
TL;DR: In this article, the magnetic field integral equation (MFIE) with the use of vector triangular basis functions has been developed, and the 1/R2 singular behavior is extracted from the integral, and closed-form expressions are given for the singular terms.
Journal ArticleDOI
Nonuniform Luneburg and two-shell lens antennas: radiation characteristics and design optimization
TL;DR: In this paper, a GA with adaptive cost function is implemented to obtain the optimal design of a non-uniform Luneburg (1964) lens antenna, where the GA optimizer simultaneously determines the optimal material and its thickness for each shell by controlling the gain and sidelobes envelope of the radiation pattern.
Proceedings ArticleDOI
Effect of textile materials on wearable antenna performance: a case study of GPS antennas
TL;DR: This study focuses on the characterization of different synthetic fabrics suitable for circular polarized micro-strip antennas, and special attention is paid to GPS antennas.
Journal ArticleDOI
A low profile single dipole antenna radiating circularly polarized waves
Fan Yang,Yahya Rahmat-Samii +1 more
TL;DR: In this paper, a low profile single dipole antenna that can generate circularly polarized (CP) radiation patterns was proposed, which was achieved using a specially designed artificial ground plane: a thin grounded slab loaded with periodic rectangular patches.
Proceedings ArticleDOI
Wearable antennas in the vicinity of human body
TL;DR: This paper presents the first in-depth results concerning the textile antenna performance in the vicinity of the human body and calculates peak and averaged SAR over 1 g tissue at the 2.4 GHz ISM band.
