Chessboard Focal Plane Array for a CMOS-Integrated Terahertz Camera

This article presents the development of a focal plane array (FPA) for terahertz imaging applications with a near diffraction-limited resolution achieved through a very tight sampling of the focal plane. The antenna array is integrated with direct detectors in a 22-nm CMOS technology and operates from 200 to 600 GHz. The tight sampling of the...

Nonlinear model predictive control for improving range-based relative localization by maximizing observability

Wireless ranging measurements have been proposed for enabling multiple Micro Air Vehicles (MAVs) to localize with respect to each other. However, the high-dimensional relative states are weakly observable due to the scalar distance measurement. Hence, the MAVs have degraded relative localization and control performance under unobservable...

UItra-Wideband Communication and Relative Localisation for Swarming Robots: UItra-Wideband Communication and Relative Localisation for Swarming Robots

A robot swarm of zebros (Dutch: ZEs Benige RObots) is being developed at the TU Delft, with the purpose of forming a large self-deploying sensor network that survey remote locations without the need for any pre-existing infrastructure, or be used for evaluating swarming algorithms in the field. Towards this goal, zebros need to be able to...

Ultra wideband omnidirectional discone antenna for WLAN applications

The focus of this thesis is to design a dielectric covered discone WLAN antenna working under the protocols of IEEE802.11 a/b/g/n. It has the wideband operation of discone antennas and the compact dimensions of dielectric resonator antennas which is compatible with the latest main protocol WLAN applications. This antenna has an ultra-wide...

Compressive Sampling for Wireless Communications

Wireless communications is undergoing massive development in all forms of its manifestations. In the field of short-range communications, technologies like ultra- wideband (UWB) systems are promising very high data rates, fine timing resolution and coexistence with other physical layer standards. Along with these benefits, the promise of low...

Error Control Coding Schemes for Ultra-wideband Impulse Radio Systems

Ultra-wideband (UWB) is a promising technology that offers a potential solution for the data rate, cost, power consumption and physical size requirements of the next generation wireless devices. UWB may also play an important role in the realization of future heterogeneous networking. This technology has recently gained significant interest from...
