We present a new technique for designing low-profile planar microwave lenses. The
proposed lenses consist of numerous miniature spatial phase shifters distributed over a …

A novel array antenna with a flat-shoulder shaped radiation pattern is proposed as the
transmitting antenna for 77 GHz automotive radar application. When it is used in an …

Applications of frequency selective surfaces (FSSs) for transmitarray antennas (TAs) are
investigated. Two broadband polarization-insensitive FSS elements are proposed and their …

In this communication, a novel substrate integrated waveguide slot array with flat-shoulder-
shaped radiation pattern is introduced for both 77 GHz automotive medium-range radar and …

This paper presents the performance of multilayered half Maxwell fish-eye (HMFE) lenses
fed by aperture-coupled microstrip patch antennas. Manufacturing techniques are reviewed …

Transmit-array (TA) design for circular polarization made by all metal is presented in this
communication. The proposed TA consists of numerous cross-slot elements. The simulation …

A linear array antenna comprising circular-shaped patches fed by slotted substrate
integrated waveguide is proposed. The slotted circular-shaped patch operates at the quasi …

The creation of artificial structures with very narrow spectral features in the terahertz range
has been a long-standing goal, as they can enable many important applications. Unlike in …

A new approach to high performance patch antenna at millimeter wave, especially 77 GHz
of frequency for automotive applications, is introduced. The proposed antenna is composed …

The off-axis performances at 77 GHz of multilayered half Maxwell fish-eye (HMFE) lenses
fed by an open-ended waveguide is describes. When moving the feed with respect to (wrt) …
