Integrated on-chip antennas for communication on and between monolithic integrated circuits

The rate of signal transmission on or between monolithic integrated circuits is limited by the cross-talk and the dispersion due to the wired interconnects. The bandwidth limitations can be overcome by wireless chip-to-chip and on-chip interconnects via integrated antennas. In this work the utilization of the electronic circuit ground planes as radiating elements for the integrated antennas has been proposed. This allows for optimal usage of chip area, as the antennas share the same metallization structure as the circuits. By exciting the interconnects between the patch areas in transmission line modes as well as in antenna modes, the interference between signals from circuit to circuit and antenna excitation signals is minimized. This has been achieved by inserting a transformer in the antenna feeding network. Examples of possible antenna and feeding structures have been investigated numerically. Scaled prototypes of the integrated antennas have been manufactured and measured.
