Abstract:

Nowadays, antennas at microwave and terahertz frequency are used in a wide range of applications, such as mobile phones, communication systems on aircraft, ships and vehicles, medical applications, remote sensing, and so on. Demands on antenna design like small physical size, low weight, wideband and multiband, reconfigurable capabilities are increasingly required. Micro-machined technology can satisfy the needs of modern antenna designs.

 

This proposal first shows a 3D cube antenna at 10 GHz using Silicon-based micro-machined fabrication method of which the 3D cubic shape allows IC packaging inside the cube’s hollow interior. The 3D structure is also beneficial in opening up the internal volume for other uses, such as storage for batteries. This proposal also designs Silicon-based micro-machined THz antennas integrated with waveguide and probe housing at WR 6.5 (110-170 GHz) and WR 2.2 (325-500 GHz). These proposed antennas are for field-replaceable far-field and near field applications, which means that the antenna chip is replaceable to generate different far fields based on different demands using a single waveguide-feed probe housing.
