Investigation of novel on-chip antennas for wireless applications and miniaturized radar sensors

OBS! ANSÖKNINGSTIDEN FÖR DETTA EXJOBB HAR LÖPT UT.
BACKGROUND:
With ever increasing frequencies in communication technology and remote sensing, and with the need for miniaturization and the decrease of cost, it is getting increasingly attractive to integrate antennas directly on-chip, with the requirement of small chip area consumption while maintaining the required antenna specifications in gain, bandwidth, beam width, side lobes. Typical applications are highly-directive, re-configurable point-to-point communication links, and 77GHz scanning automotive radar, with the final goal of having a radar-on-chip.

OBJECTIVES:
The objective of the thesis is to investigate concepts of on-chip antennas with high directivity and small area consumption. Previous work has already identified some suitable antenna concepts, which have to be further investigated by simulations and by prototype manufacturing and measurement evaluation. This project will be carried out as a part within a larger Scandinavian research initiative, involving universities in Finland, Sweden, and Norway, as well as 10 supporting industrial partners.

TASKS:
The student will investigate suitable antenna concepts by simulations (ANSOFT HFSS), by building and measuring macroscopic prototypes (5-20 GHz), and by designing on-chip antenna elements (77 GHz). The thesis will be carried out at KTH - Royal institute of Technology, School of Electrical Engineering, Microsystem Technology Lab.

REQUIREMENTS:
- study programme in electrical engineering, technical physics, or equivalent
- basic knowledge in microwave engineering
- basic knowledge in antenna design
- basic knowledge of microwave simulation software is advantageous

TIME:
6 months; start as soon as possible (Dec. 2007)

For good candidates, the continuation as PhD student in the field of RF/microwave micro-electromechanical systems is possible.

SUPERVISION:
- Joachim Oberhammer (Assoc. Prof.): co-supervisor and examiner
- Nutapong Somjit (PhD student): main supervisor
