چکیده
This paper reports the design, fabrication and measurement techniques for a set of low-loss slotted waveguides. The waveguides are fabricated based on micro metal additive manufacturing technology. They were layer by in one piece without need post-fabrication assembly. As examples, straight WR-3.4 (220-330°GHz) WR-2.2 (330-500°GHz) bands tested. Measurement results show insertion loss per unit length is 0.0615-0.122°dB/mm 0.116-0.281°dB/mm, respectively.

Plastic 95-GHz rectangular waveguides by micro molding technologies
A plastic, 95-GHz rectangular waveguide with an integrated plastic flange has been successfully demonstrated using micro hot embossing and electroplating technologies. Two prototype devices with integrated flanges on both ends have been tested using an Agilent PNA 5250 network analyzer. The prototype with non-metallized flange shows return loss s11 and insertion loss s21 values of −21.5 and −1....
متن کاملA Very Low Loss 220–325 GHz Silicon Micromachined Waveguide Technology
This paper reports for the first time on a very low loss silicon micromachined waveguide technology, implemented for the frequency band of 220 – 325 GHz. The waveguide is realized by utilizing a double H-plane split in a three-wafer stack. This ensures very low surface roughness, in particular on the top and bottom surfaces of the waveguide, without the use of any surface roughness reduction pr...

متن کاملIntegrated Micromachined Waveguide Absorbers at 220 – 325 GHz
This paper presents the characterization of integrated micromachined waveguide absorbers in the frequency band of 220 to 325 GHz. Tapered absorber wedges were cut out of four different commercially available semi-rigid absorber materials and inserted in a backshorted micromachined waveguide cavity for characterization. The absorption properties of these materials are only specified at 10 GHz, a...
