A new antenna element type based on the open-ended ridge gap waveguide (RGW) is proposed for beam-steering phased array applications. This element type is of a particular interest at high mm-wave frequencies (≥ 100 GHz) owing to a contactless desig

International audience; In this paper, we propose a discrete time transfer function approximation for the reduced complexity parallel least mean square (RC-pLMS) adaptive beamforming algorithm. The RC-pLMS is built using a single least mean square (L

A single-layer high-gain dipole antenna array with a bidirectional radiation pattern based on parallel-strip line

Autor: Zhe Wu, Yu Yun, Håkan Lennerstad, Zhuang Miao

Publikováno v: IET Microwaves, Antennas & Propagation, Vol 15, Iss 3, Pp 323-331 (2021)

A single-layer dipole antenna array with quasi-Yagi configuration has been proposed and demonstrated, which provides a dual radiation pattern with the same sense. This antenna is mainly composed of a substrate-supported parallel strip line (PSL) and
