An f/0.27 High-Gain Lens Antenna for Ultrasmall Platforms at THz Frequencies

The development of a low focal number and low-mass lens antenna is presented that enables terahertz spectroscopy applications on ultracompact platforms. The antenna operates efficiently over a 20% fractional bandwidth, from 450 to 550 GHz, with a gain of 50 dBi at 500 GHz. The antenna consists of a hyperbolic silicon lens that is placed in a...

Space of Signal

The project Space of Signal in a speculative design that explores the potential impact of 5G signal on built environment. As proved by the conducted research, the Presence of 5G Transmitter will encourage the act of gathering of e-businesses in the close proximity to signal source, as this will remain the guaranty of reliable and stable 5G...

Radar Based Human Vital Sign Detection In Cars: A System Analysis

This thesis analyses different radar systems for sensing chest movement to detect human presence inside a car. The detection in this thesis is limited to sensing breathing rate, although heartbeat detection is considered a possibility. A comparison is made between CW-, FMCW-, pulsed- and UWB pulsed radar. UWB pulsed radar was chosen to be a...

Development of custom multi-band LTE antenna for telemetric applications: Custom design vs. existing commercial LTE antennas

The final goal of this thesis is to figure out if it is possible to design an eight-band LTE antenna for <$0,20 with the same performance, quality and tunability as the current available eight-band LTE antennas. In the introduction the state of the art is presented where the most common currently available comparableantennas and modules are...

Design and analysis of non-uniform MIMO array for interference suppression and automotive applications

Automotive radars play a very important role in reduction of traffic accidents and casualties by making the vehicle fully self aware of its surroundings. For the vehicle to be fully self aware multiple sensors or radars have to placed in close proximity of each other on the body of the automobile. This will lead to interference between the...
