Nowadays, recent Integrated Circuit Technology demands a minimum metal fill inclusion across the entire die of each functional layer to have uniform planarity. It is challenging to numerically simulate the real structure using Electromagnetic (EM) solvers because the mesh size of an EM solver is inversely proportional to the number of vertices...

Front-end Monolithic Microwave Integrated Circuits (MMICs) have recently become commercially available for frequencies above 100 GHz. However, achieving low-loss and broadband interconnections between the antenna and MMICs is challenging for integrated front ends at these frequencies. This thesis presents the characterization of a flip-chip...

A new antenna measurement setup, the Antenna Dome, is being developed, which can provide real time antenna and beamformer measurements. In order to be able to validate this setup, an existing beamforming system will be will be extensively studied and characterized. Multiple measurement setups will be used, providing multiple measured...

de Graaf, John (author), Mao, Rui (author)
In this thesis, the realization and qualification of an anechoic dome chamber for 5G antenna’s is discussed. As with audio, where no echoes or noise from outside is wanted when listening to music, when characterizing an antenna it must be prevented to get internal reflections or electromagnetic (EM) radiation from outside. For this reason, a...

In the ADome project, a truncated icosahedron is used as a frame for multiple antenna nodes. These nodes are used to measure the radiation pattern of an antenna-under-test located in the center of this dome. Since these antennas can be placed anywhere in the ADome by the user, a calibration system is necessary to find the spherical coordinates...

This thesis focuses on improving the readout of the ADome by implementing MCUs at each antenna probe, enabling local sampling and memory storage. The serial communication protocols CAN, SPI and I2C are considered and compared with one another. Ultimately, CAN is decided due to its robustness and simplicity which make the system cheap and ensures...

The accuracy of a true-RMS detector board based on the Analog Devices LTC5596 is determined by measuring the input power and the output voltage. A number of samples of the output voltage is taken and the mean and standard deviation is shown. These measurements are done for single-tone excitation with a direct connection and over-the-air setup,...

The commercialization of millimeter wave frequencies for the 5G New Radio standard requires time and cost -effective testing equipment. The over-the-air measurement setup developed at the TU Delft (ADome) is able to reduce measurement time, by positioning multiple fixed sensing nodes around the antenna-under-test. To expand the system...

Due to the earth’s population growth and the increased living age of a person, more and more people could deal with medical problems. Early detection of health related problems in both healthy and people with medical problems, will catch problems early and prevent the need for more costly procedures. One of these medical problems is concerning...

Until now parameter analysers for Organ-on-Chips (OoCs) have needed bulky multi-probe setups that do not fit in biological research labs. For this reason a bachelor graduation project was proposed to get one of the sensors designed by the Electronic Components, Technology and Materials group (ECTM) out of the lab and into the hands of potential...

Problems in drug development and personalised disease treatments are the main impulse for the development of OoCs. At the Electronic Components, Technology and Materials (ECTM) group at TU Delft an OoC sensor has been developed and the design is now at a stage where a system can be developed to take the sensor out of the initial research...

Real-time cell culture media monitoring can be conducted by Organ-on-Chip (OoC) ion-sensitive floating-gate field-effect transistor based sensors (ISFGFET). A method of modelling the sensor is described and implemented in the Advanced Design System (ADS) design and simulation software. The model is validated using measurement data of the sensor...

To solve extant complications with standard wafer-probing techniques, such as probe-to-probe coupling and probe-tip deterioration, a novel probe tip device has been designed and verified by means of 3D EM-simulation for the 220-325 GHz frequency band. The new probing technique uses an on-wafer cavity-backed slot to couple the signal to a tapered...

The recent development of commercial phased array antennas for 5G at mm-wave frequencies (20 GHz to 60 GHz) introduces new challenges for radiation pattern characterization. Since these systems aim to employ active beamforming to steer the datastream to specific users, a single base station should be capable of deploying multiple beams...

This thesis work focuses on the development of reference data and visualization software to implement a user friendly probe to image the electrical parameters (i.e., permittivity) of biological materials, such as the skin. The reference data is used for the creation of a lookup table that can be used to quickly derive the relative permittivity...

Millimeter-wave passive radiometers have earlier been designed in III-V integrated circuit (IC) technologies, due to their higher carrier mobility when compared to silicon, resulting in higher transit frequencies (fT) thereby enabling to operate at higher frequencies. However, increased fT in SiGe BiCMOS technology has generated interest for...
