This communication presents a gain-equalized-band Rotman lens-fed antenna by using
phase gradient transmission lines (PGTLs). With PGTLs, the variation trend of the output …

Ridge gap waveguide (RGW) technology is used in the design of a frequency scanning
antenna with high gain and directivity. A Quasi-TEM horn with shaped ridge is designed as a …

This article proposes an innovative method for extending the scan range of phased arrays
based on Rotman lens by a factor two. The main objective is to take advantage of the …

A retrodirective beamforming system (BFS) based on a Rotman lens is proposed for far-field
wireless power transfer at Ka-band. The true-time-delay property of the Rotman lens allows …

A frequency-scanning antenna array of nonresonant slots with uniform slot field distribution
is designed using the ridge gap waveguide (RGW) technology. The slots are separated by …

This paper presents the design and simulations of a Rotman lens for use at 60 GHz
frequency band. This lens will be used as a feeding network for a multi-beam antenna. Both …

In this paper, a novel microwave power divider/combiner based on Gysel structure and ridge-
gap waveguide (RGW) technology is proposed and simulated. The proposed structure has …
