Investigation of LTCC leaky wave antenna operated in mm-wave band

This paper presents the challenge involved in designing LTCC leaky wave antenna operated in mm-wave band. Taking account a possibility of using LTCC technology in the mm wave, some advantages and limitations of its technology in these frequency band are described. Moreover the transition between waveguide to designed antenna is presented and the simulation results of each parts of the structure are shown. Moreover some manufactured parts of the antenna with using LTCC technology is shown. The antenna is optimized to obtain a minimum radiation pattern squint in all operated frequency bandwidth.
