-This work presents the experimental realization and the performances of a magnetostatic microwave straight edge tunable resonator (SER) placed on a silicon membrane. The aim of this approach is to study a miniaturised device, integrable in a planar micromachined microwave circuit. S 11 and S 21 parameters of this device are presented for different magnetic bias fields, exhibiting frequency tunability between 4.2 GHz and 7.25 GHz. The utilization of silicon membranes to support these devices offers important openings toward the integration of magnetostatic wave devices with micromachined structures.

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 forf=27 GHz andf=38.5, GHz, respectively. The CRLH antenna onf=27 GHz shows a return loss ofRL<−18.78 dB atf=26.88 GHz. The −3 dB radiation characteristic beamwidth was approximately 37° and the gain wasGi=2.82 dBi. The CRLH antenna onf=38.5 GHz has a return loss ofRL<−38.5 dB atf=38.82 GHz and the −3 dB radiation characteristic beamwidth of approximately 17°. The gains wereGi=1.08 dBi atf=38 GHz andGi=1.2 dBi atf=38.6 GHz. The maximum measured gain wasGi=1.75 dBi atf=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.
