30GHz self-assembled highly-efficient on-chip monopole antennas
A novel monopole antenna made from an out-of-plane stressed cantilever beam is presented. The radiating element is isolated from a low-resistivity silicon substrate with a ground plane and thus high radiation efficiency of more than 50 can be achieved even with a CMOS-grade silicon substrate. The proposed antennas can be readily fabricated by a conventional IC fabrication process, which enables a high level of integration and low cost. Our experimental results of the monopole operating at 30GHz agree well with our theoretical predictions. 2008 The Institution of Engineering and Technology.
