Wireless inter-chip and intra-chip communication

Chip-to-chip and intra-chip wireless communication via integrated on-chip antennas has the potential to overcome the limitations of broad-band signal transmission on or between monolithic integrated circuits. In this work the use of same chip area for antenna patches and circuits is investigated. This has been accomplished by using antenna patch areas also as ground planes for the electronic circuits. Interference between circuit and antenna signals can be minimised by exciting the circuit interconnects in transmission line modes and the antennas in antenna modes. Examples for possible realisations of such structures are given and their electromagnetic properties are modelled numerically.
