| Research Abstract |
We have designed and fabricated a circularly-polarized patch antenna fed by coaxial structure through a hole, which is realized on a 200um-thick resin over a 5mm-square silicon chip coated with 2um-thick copper. The radiation efficiency of the antenna is measured by a reverberation chamber with uncertainty of ±3％. It is 75% and has good agreement with the designed value. The loss of the 320um-long coaxial structure has been confirmed to be 0.2dB. We have also developed the system to measure radiation patterns using optical fibers in the 50GHz band.
