60 GHz grounded-coplanar-waveguide-to-substrate- integrated-waveguide transition for RoF transmitters

Electronics Letters, vol. 50, no. 1, pp. 34-35, DOI: 10.1049/el.2013.3533, 2014.


Kurzinfo: A novel transition from a grounded-coplanar waveguide to a substrate integrated-waveguide (SIW) is presented featuring a fully planar bias tee for the development of 60 GHz radio-over-fibre photonic transmitters for indoor applications. The transition is intended to serve as a connection between a 60 GHz photodiode chip and SIW antennas suitable for indoor data distribution. Simulations show that in the whole 57–64 GHz communication band, the return loss (RL) is at least 15 dB, whereas the insertion loss (IL), is < 0.9 dB. Measurements of a back-to-back configuration confirm the numerical results, with a IL of ∼2 dB and a RL > 12 dB.

100 gigabits per second and more for high-speed wireless Internet service

Magazin: ForschungsForum Paderborn, April, 2014.

Kurzinfo: We live in the age of high-speed Internet. In particular, portable computers such as smartphones, tablets and notebooks need ever faster wireless Internet access in daily use. The rapidly growing number of users and applications requires the development of ever more innovative mobile terminals and technologies as well as ever higher transmission rates and transmission qualities (or quality of services). An increasing need for high-speed wireless networks is apparent, e.g., in consumer and home electronics. Examples are wireless ultra-high definition and 3D TV screens, wireless connections to peripherals such as video players or hard disks, data synchronization and general wireless data transmission within computer networks and clusters.

Invited presentation, 8th German Microwave Conference 2014 (GeMiC 2014), Aachen, Germany, March, 2014.

Kurzinfo: Im Vortrag werden kurz die Herausforderungen dargestellt, die eine extrem hohe Datenübertragung an die Teilsysteme, RF-Frontend, Basisbandprozessor und MAC-Prozessor stellten. Die unterschiedlichen Ansätze aus den Einzelprojekten werden kurz dargestellt und diskutiert. Insbesondere wird auch auf die Aufteilung der Basisbandbearbeitung zwischen dem analogen und digitalen Schaltungsteilen eingegangen. Hier könnte möglicherweise ein Paradigmen-Shift hin zu mehr analogem Rechnen interessant werden.

Wireless 100 Gb/s: PHY layer overview and challenges in the THz freqency band

In Proc. IEEE Wireless and Microwave Technology Conference (WAMICON 2014), Tampa, Florida, USA, June, 2014.


Stichwort: 100 Gb/s , wireless, PSSS, PHY layer, Terahertz

Kurzinfo: There is a continuous increase of bandwidth-demanding services such as ultra HDTV, 3D TV, etc. which will require data rates up to 100-400 Gb/s for short range wireless communication. This paper introduces a novel mixed-mode design where both analog and digital domain design is considered, which helps in the reduction of power consumption. Parallel Sequence Spread Spectrum (PSSS) is used for physical layer (PHY) baseband technology, which considerably alleviates both transmitter and receiver design.

Systematic Design Method of a Mobile Multiple Antenna System Using the Theory of Characteristic Modes

IET Microwaves, Antennas & Propagation, vol. 8, issue 12, pp. 887 – 893, DOI: 10.1049/iet-map.2013.0534, 2014.


Kurzinfo: In this study, the authors present a systematic design method of a three-port multiple-input–multiple-output antenna system for small terminals, such as smart phones based on the selective excitation of orthogonal chassis modes. The underlying idea is based on the theory of characteristic modes (TCM). Selective excitation of these modes is realised by sets of non-resonant inductive coupling elements integrated at predefined positions into the printed circuit board (PCB) layout. Stripline feed networks also integrated within the multi-layer PCB layout care for a good impedance match to 50 Ω. The design method of this antenna system is a straight forward application of the TCM and is therefore of general interest for the design of small terminal antennas. Furthermore, owing to the electrically small couplers that require only limited area at the outer edge of the PCB the method represents an interesting solution with the clear potential to be extended to more ports. The realised prototype resembles the predicted performance very well and therefore proves the applicability of the proposed method.
