Study of D-band LTCC Leaky Wave Antenna Optimized for Broadside Radiation
MetadataShow full item record
This paper presents the design, fabrication and measurements of a Low Temperature Co-Fired Ceramic leaky wave antenna optimized for broadside radiation. The antenna consists of two DuPont 9k7 material layers. The thickness of each layer is approximately 115 um. The bottom layer plays the role of the main substrate and a top layer is used for creating a corrugated structure. The developed antenna operates in the frequency range of 125 GHz – 135 GHz with a minimized radiation pattern squint below 8 degrees in the whole operating bandwidth. The antenna reflection coefficient S11 is less than -10 dB in the operating frequency bandwidth and the maximum measured antenna gain is 9.9 dBi. Moreover a study of different antenna radiating structures and their capability of broadside radiation and reflection coefficient properties are discussed.
