60-GHz LTCC helical antenna

摘要

In this paper, we present a 60-GHz helical antenna element fabricated using low temperature co-fired ceramic (LTCC) technology. The flexible via hole distribution is fully utilized to achieve a planar helical antenna in LTCC to obtain wideband circular polarization performance. The grounded coplanar waveguide (GCPW) to stripline (SL) transition is utilized for probe station measurement.
