Design of a Conformal Ground Surveillance Radar (GSR) Antenna
Chase, Brian (Master thesis, 2013)Ground Surveillance Radar (GSR) requires a phased array, conformal cylindricalantenna solution that has specific features (electronically scan the azimuth andelevation, with angular width of ca. 6° in both directions, and ... -
Design of a practical and compact mm-wave MIMO system with optimized capacity and phased arrays
Cella, Tommaso; Orten, Pål; Ekman, Torbjörn (Journal article; Peer reviewed, 2014)In this paper we evaluate the feasibility of short range outdoor mm-wave MIMO links in the 70 GHz portion of the E-band (71–76 GHz). We use phased arrays in order to strongly reduce the impact of the multipath components, ... -
High Capacity and High Coverage mm-Wave Multi-Antenna Systems
Cella, Tommaso (Doctoral thesis at NTNU;2015:225, Doctoral thesis, 2015)The future generations of communication systems will require gigabit per second links. In order to provide the expected capacity, several possibilities have been investigated. One of them is the use of millimeter waves. ... -
MIMO Geometry and Antenna Design for High Capacity and Improved Coverage in mm-Wave Systems
Cella, Tommaso; Orten, Pål; Hjelmstad, Jens (Journal article; Peer reviewed, 2013)We show a way to optimize the capacity and at the same time achieve high coverage in LOS for a mm-wave system indoor. We optimize MIMO with regard to maximum Shannon capacity for a pure LOS channel. We describe the general ...
