Millimeter Wave Antennas and Beamforming for Wireless Communication and Imaging Systems
This presentation explores the development of compact, high-gain, broadband millimeter-wave antennas utilizing printed ridge gap waveguide technology to meet the growing demand for high data rate and low latency applications in next-generation wireless communication, sensing, and imaging systems.
Overview
With the improvement of mobile communication technologies and their broad applications, mobile communication will have more impact on our life. Such systems will support a variety of personal communication services with high-data rate and very low latency applications. To achieve such demands, many proposals associated with the development of emerging wireless and imaging systems identify a set of requirements for which different technological directions are independently emerging. One direction is utilizing the millimeter-wave (mm-Wave) frequency bands where more spectrums are available. Due to the corresponding smaller wavelength, mm-wave frequencies offer the advantage of physically smaller antennas and circuits as well as the availability of much wider bandwidth compared to microwave frequencies. In addition, they provide additional spectrum for wireless communications. The planned cellular networks base stations and mobile devices will essentially make use of mm-wave frequency bands to meet consumers’ ever-growing demand for high data rate and capacity from wireless service providers. Design requirements for related antennas include highly directional patterns – for long transmission range and high detection sensitivity - and size reduction with a suitable impedance matching bandwidth. This talk will address the market demand for compact highly efficient antennas for next generation wireless communications, sensing and imaging systems. The main part of the talk will focus on investigation and development of mm-wave high gain broadband antennas and beamforming that cover multiple mm-wave frequency bands to serve several applications. The work is utilizing the state-of-the-art guiding structures, especially printed ridge gap waveguide (PRGW), that have low loss and minimal dispersion compared with traditional PCB-based structures. It will focus on the necessary components for a beamforming antenna system which is implemented using PRGW technology.
