The paper presents two composite right/left-handed (CRLH) coplanar waveguide (CPW) zeroth-order resonant (ZOR) antennas which were designed, processed, and electrically characterized for applications in the millimetric wave frequency range. Two CRLH antennas were developed for  GHz and  GHz, respectively. The CRLH antenna on  GHz shows a return loss of  dB at  GHz. The −3 dB radiation characteristic beamwidth was approximately 37° and the gain was  dBi. The CRLH antenna on  GHz has a return loss of  dB at  GHz and the −3 dB radiation characteristic beamwidth of approximately 17°. The gains were  dBi at  GHz and  dBi at  GHz. The maximum measured gain was  dBi at  GHz. It is, upon the authors' knowledge, the first report of millimeter wave CRLH antennas on silicon substrate in CPW technique for use in mm-wave monolithic integrated circuit.
