Design and Test of: Wide Band and Highly Polarized Antenna for 60GHz

Sammanfattning: In this work  high gain antennas are investigated for the 60 GHz frequency. The goal is to produce a high bandwidth point-to-point wireless network that could enable improved and new features in embedded systems used to detect particles in high energy physics. A literature study was performed aiming at simple, high gain, highly polarised antennas. Complex designs were grouped into three different groups: flat antenna design, build-up design and multi-antenna design. The multi-antenna design was found to have the simplest design and manufacturing but also feature larger antenna area. Three different designs were produced and tested, standard patch antenna, long patch antenna and a Vivaldi antenna. Manufacturing of a 4-patch antenna was also tested. All three demonstrated expected properties, the Vivaldi shows the best gain while the long patch antenna is slightly below the standard patch antenna. A forth design implementation was also tested using a 3D-printed lens. A lens can increase gain and allow changing beam direction. A lens was design and tested, the results showed an increased gain but with varying results at angels. Antennas were designed and manufactured using simple etching technique showing that further research can be done using simple and easily accessible techniques. Both antenna and lens show good properties and should be further investigated and validated.
