Abstract :
A type of waveguide feed Terahertz slot array antenna with a plastic substrate body structure is proposed in this paper. Slots are produced by periodically cutting a copper plate. Implementation of the plastic based waveguide body offers a better directivity and radiation efficiency than the conventional metallic waveguide, and lower inner attenuation can be achieved. Full-wave simulation showed that the waveguide feed W-band slot array antenna works at 88.4GHz with a 10dB bandwidth of 16.4GHz and the maximum directivity is 13dBi. Better antenna directivity can be achieved by employing antenna array.
