Millimeter-wave planar log periodic antenna for on-chip wireless interconnects

The performance of large multi-core chips have been limited by high power dissipation and latency problems associated with conventional interconnect topologies. On-chip wireless interconnect architectures with associated on-chip antennas have been recently investigated as a possible alternative to wired interconnects. In this paper, we propose the design for an on-chip planar log-periodic antenna with wide bandwidth and end-fire directivity at millimeter and/or microwave range of frequencies to improve the signal transmission characteristics of wireless interconnects. A two-port antenna network is simulated for 60GHz in HFSS and the radiation pattern and the scattering matrix parameters are presented.
