Embodiment Construction

[0072] Embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals may denote the same elements, and the size of each element may be exaggerated for convenience of description. Also, descriptions of well-known functions and constructions may be omitted for clarity and conciseness.

[0073] Terms such as "first", "second" and "third" may be used herein to describe various elements, components, regions, layers and / or sections and should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first element, component, region, layer or section could be termed a second element, component, region, layer or section without departing from the scope of the present disclosure. As used herein, the expression "and / or" includes any and all combinations of one or m...

Abstract

Disclosed is a ridge guide waveguide including a conductive base, a conductive ridge protruding upward from the conductive base and extending along a predetermined wave transmission direction, an upper conductive wall located over the conductive base and the conductive ridge and spaced apart from the conductive ridge by a gap, and an electromagnetic bandgap structure arranged adjacent to the conductive ridge between the conductive base and the upper conductive wall.

Description

technical field [0001] The present disclosure relates generally to wireless engineering and, more particularly, to a printed circuit board and Ridge Gap Waveguide (RGW) based multilayer mmWave antenna array. Background technique [0002] With the rapid development of communication technology, there is an ever-increasing user demand. Currently, systems that are actively developed using communications in the mmWave frequency band include: data transmission systems operating in the 28 gigahertz (GHz) and 60 GHz frequency bands; Long-range wireless power transfer (LWPT) systems operating in the 24GHz band for scientific and medical (ISM); and automotive radar systems operating in the 24GHz and 79GHz bands. All of these and similar systems require simple and reliable components that are efficient, practical and suitable for mass production. Among these components, the antenna occupies an important place. Requirements for mmWave antennas include: low antenna loss, high gain, fl...
