James will be presenting some of his work on millimetre-wave systems, a frequency range which has gathered a lot of interest over the past decade, primarily due to the availability of significantly more bandwidth compared to the traditional highly congested microwave bands. The lecture will focus on antenna design approaches, which often dictates the system architecture, whilst considering the trade-offs in complexity, performance, size and cost of the overall system. Different design approaches for low-cost and high-performance systems will be discussed, whilst considering new technology and manufacturing advances.
The lecture will cover real-world examples developed by Plextek where contrasting requirements throughout the system have led to novel antenna array solutions, whilst also considering future millimetre-wave system developments to address future requirements in wireless communications and sensing solutions.
Dr James Henderson, Plextek Services Limited
Dr James Henderson is a lead consultant at Plextek specialising in highly integrated microwave and millimetre-wave electronic systems. His work has led to the development of several millimetre-wave radar systems deployed throughout the world (and space) for civil and research applications, as well as for medical products and future wireless communication system concepts.
James’ interest in this area led him to complete an Engineering Doctorate at Queen Mary University of London last year, focussing on reconfigurable millimetre-wave antenna arrays using novel materials and approaches. His work has been published and presented in many technical papers in IEEE-endorsed journal and conferences.
