Millimeter-Wave Suspended Silicon-on-Glass Tapered Antenna With Dual-Mode Operation

PROJECT TITLE :

Millimeter-Wave Suspended Silicon-on-Glass Tapered Antenna With Dual-Mode Operation

ABSTRACT:

A highly efficient millimeter-wave (mmW)/Terahertz (THz) dielectric antenna is proposed. The proposed suspended tapered antenna [created of high resistivity silicon (Si)] is fabricated in an exceedingly new mmW/THz integrated technology platform referred to as silicon-on-glass (SOG). The fabrication process makes the tapered antenna with deep reactive ion etching of the Si layer of the SOG platform, whereby a part of the glass substrate below the antenna tapered section is etched. The glass substrate below the antenna is etched in hydrofluoric acid (HF 49percent) before bonding to the Si wafer. The antenna is meant to radiate both $E_x$- and $E_y$-polarizations over the frequency band of 110–130 GHz and features extra benefits together with highly linear polarization, high-directivity, integrability, and low-value fabrication. Numerical and experimental results are presented to validate the high-performance proposed antenna. Experiments show gains of seventeen.five dBi at 115 GHz and 18.three dBi at 128 GHz for $E_x^11$- and $E_y^11$-modes excitations, respectively. These two polarizations show measured efficiencies of 94% and 99p.c, respectively.
