    Sammanfattning : Wireless sensors are used widely for condition monitoring in electric machines. The metal enclosure of an electric motor restricts the signal from sensors to radiate outside. The signal from the metal cavity needs to be guided to the only opening in the enclosure, through a narrow gap between the stator and the rotating rotor. LÄS MER

  3. 2. Ka-band 2D Luneburg Lens Design with Glide-symmetric Metasurface

    Sammanfattning : A Luneburg lens is a beam former that has two focal points where one isat the surface and the other lies at innity. It is a cheap passive steerableantenna at high frequencies. In this thesis, a 2D at-prole Luneburglens with all-metal structure is designed for Ka band. LÄS MER
