Application of a Novel Micromachining Process to Millimeter Wave Circuit Fabrication

MicroFab Research (MFR, Inc.) proposes to apply the techniques of micromachining to aid in the fabrication of millimeter wave components, thereby reducing manufacturing expenses. Many microwave applications such as radar and communication systems would be improved by shifting to higher frequencies, provided new lower cost manufacturing techniques can be found. A manufacturing technique is presented whereby machining costs for millimeter wave components may be significantly reduced. Millimeter wave technology may be applied to many commercial microwave applications such as communications or RADAR, however, the cost is currently prohibitive in many cases. Higher frequencies allow smaller antenna size, wider unoccupied bandwidth, and lower noise. In particular, automobile collision avoidance radar, position sensors, and wireless communications have the potential for high volume markets provided costs can be reduced.
