Abstract

A repeater device comprises a periodic array of alternating metallic phase shifting elements, the array being periodic in at least one axis, formed on a first surface of a dielectric substrate, with an opposite surface of the dielectric substrate having a ground plane formed thereon, wherein each phase shifting element provides from 0-degree to 360-degree phase shifting in the microwave frequencyrange. The repeater device can be utilized in a microwave network.

Description

Technical Field [0001] The present invention relates to a passive repeater device for use in microwave networks, the passive repeater device comprising a periodic array of phase-shifting elements. Background Technology [0002] Modern cellular networks encompass geographical areas covered by wireless signals, known as macrocells. Within a macrocell, base stations enable cellular users to connect to the core network and communicate with other users or access information on remote servers. Due to the availability and low cost of smartphones and laptops, mobile data traffic on wireless networks is expected to continue to increase in the coming years. In addition to regular, traditional voice communications, the increase in mobile data traffic is also driven by bandwidth-intensive, high-resolution video applications and services such as video content sites, gaming, and data transfer. [0003] When data, especially video, is transmitted over wireless channels, the quality of the r...
