Design and prototyping of radiation- and area-efficient monolithic integrated antennas

Abstract

The wireless chip–to–chip interface is an interesting alternative to wired digital buses. An important element from a wireless interconnect is the monolithic integrated antenna. On–chip antennas have to meet several restrictions - they have to cover very little chip area and they need to have high radiation efficiency in a large enough frequency range to allow for fast interchip communication. This work describes two methods for designing efficient on–chip antennas, namely using high–impedance substrate with standard thickness, or using very thin substrate. The proposed antennas have been prototyped and their parameters were verified via measurement.
