Low profile high directivity millimetrewave antenna using freeformed metamaterial

A high directivity millimeterwave antenna based on woodpile electromagnetic bandgap (EBG) material at W-band is presented. The woodpile EBG structure is fabricated using the ceramic extrusion freeforming technique with high purity alumina powder. The designed antenna can achieve a narrow beam withou...

More Information
Summary:A high directivity millimeterwave antenna based on woodpile electromagnetic bandgap (EBG) material at W-band is presented. The woodpile EBG structure is fabricated using the ceramic extrusion freeforming technique with high purity alumina powder. The designed antenna can achieve a narrow beam without using an array. The measured half power beam widths are 14 and 10 degrees for E-plane and H-plane, respectively. Measurements results are in good comparison with simulations.
