“…At 88 GHz, the maximum insertion loss is only 0.6 dB for a phase shift of 114 achieved at this frequency. Table II compares the performance of the new dielectric phase shifter with other mmW techniques in the literature [6]- [11]. This table confirms low-loss characteristics of the new SOG phase shifter as compared to other techniques.…”

A low-loss, low-cost, and compact fully-dielectric phase shifter integrated on the corrugated Silicon-On-Glass (SOG) platform is presented for the first time. In the corrugated SOG platform, the glass substrate below the high-resistivity silicon (Si) components is etched in a periodic configuration to reduce the insertion loss and enhance the field confinement inside the Si. Measured phase shifts of 111 and 129 are achieved by a device length of 5 mm at the frequencies of 85 and 100 GHz, respectively. At 88 GHz, the maximum insertion loss over a phase shift of 114 is only 0.6 dB.Index Terms-Dielectric waveguide, passive components/circuits, phase shifter.

“…State of the art results were reported from many groups [2][3][4][5][6]. At E-band (77 GHz), insertion loss amounts to about 1.75 dB per bit [7] (or, 5.8 dB for 3 bits [8]). Continuously variable phase shifters based on variably loaded transmission lines have been proposed by several groups [9][10][11], but only recently entered the millimeter-wave domain [12].…”

“…However, they are not suitable for millimeter wave frequency, including W-band, because the performance of multiple switches and the necessary lengths of the transmission line degrade the performance (Somjit et al , 2009). Stehle et al (2008) describe a phase shifter consisting of a 45° loaded-line phase shifter element, a 90° as well as a 180° switched-line phase shifter element, resulting in 3-bit RF MEMS phase shifter. For the complete device, return loss was better than −12 dB and the insertion loss was −5.7 dB at 76.5 GHz.…”
