Abstract-A technique combining the finite-difference time-domain method and the imaginary-distance beam-propagation method is used to demonstrate the discontinuity-radiation concept for a dielectric rod antenna. The field near the rod is decomposed into a guided and an unguided wave. Using the two waves, the feed and terminal patterns are evaluated. It is numerically revealed that superposing the two patterns forms the radiation field of the antenna. The decomposition technique enables us to efficiently evaluate the directivity of a long rod antenna.Index Terms-Dielectric antennas, dielectric waveguides, endfire antennas, finite-difference time-domain (FDTD) methods, finite difference methods.

“…The electromagnetic energy starts radiating when the DW width tapers along its axis. Therefore, increasing the length of the element might increase the maximum gain of the antenna element [7]. The simulated H-plane (φ=90º) and Eplane (φ=0º) gain patterns are depicted in Fig.…”

“…Various types of feeding antennas of the lens, such as horns, dipoles, planar, dielectric rod antenna, have been studied widely and used for achieving a compact size and high radiation efficiency. So far, the most practical structure is a dielectric rod antenna due to its low cross polarization, relatively high gain and potential for a very dense packaging [4][5][6]. In the case of lens antenna design, primarily two different lenses are used for realizing different goals.…”

Abstract-An advanced aspheric and asymmetric large aperture dielectric lens antenna is proposed firstly here for high resolution at Wband frequency. Large aperture and aspheric lens provides minimum focusing error and high resolution in millimeter wave quasi-optics application. To the best of the authors' knowledge we design first time 500 mm large aperture lens for W-band quasi optics application. Near field radiation pattern, beam size and focal length of the lens are obtained theoretically and experimentally as well. Dielectric rod waveguide antenna is also designed and employed as a source antenna for the lens. The measured and simulated results of the DRW antenna also show very good performance at W-band frequency, and it has 15.3 dB gain with −22.5 dB sidelobe levels at 94 GHz.
