Planar spiral AMCs integrated on 60 GHz antennas

We present a low-profile design of a planar artificial magnetic conductor (AMC) based on spiral unit cells integrated on dipole antennas. The whole system is designed and manufactured on a multi-layer packaging technology suitable for single-chip 60-GHz radio transceivers. The design projects the AMC functionality on the antenna metallization package layer subject to fixed package design rules. The integrated antenna- AMC design presented has measured impedance bandwidth much greater than necessary to cover all international 60-GHz radio bands, small form factor suitable for on-package integration, and 5 dBi gain for single elements making it ideal for small directive on-package arrays for 60 GHz radio applications.
