Metamaterial CRLH Antennas on Silicon Substrate for Millimeter-Wave Integrated Circuits

Abstract EN

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 f=27 GHz and f=38.5, GHz, respectively.

The CRLH antenna on f=27 GHz shows a return loss of RL<−18.78 dB at f=26.88 GHz.

The −3 dB radiation characteristic beamwidth was approximately 37° and the gain was Gi=2.82 dBi.

The CRLH antenna on f=38.5 GHz has a return loss of RL<−38.5 dB at f=38.82 GHz and the −3 dB radiation characteristic beamwidth of approximately 17°.

The gains were Gi=1.08 dBi at f=38 GHz and Gi=1.2 dBi at f=38.6 GHz.

The maximum measured gain was Gi=1.75 dBi at f=38.2 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.
