Integrated circuit mm-wave antenna structure

摘要

An antenna array structure is disclosed for use in receiving, transmitting, or transceiving electromagnetic radiation. The antenna array structure includes a first planar substrate with one or more grooves formed therein with at least one secondary planar substrate having an antenna formed thereon placed in one of the grooves in the first substrate. The use of this three-dimensional structure takes advantage of the inherent directionality due to the guidance of electromagnetic radiation by the secondary planar substrate. This antenna array structure provides the advantages of reduced cross talk between adjacent antennae and can readily be produced using standard silicon fabrication techniques.
