We have developed rectangular patch antennas with single-ended and balanced feed ports, respectively, for use in high data-rate millimetre wave transmission systems. The antennas were designed for the unlicensed ISM-Band at 60 GHz, and fabricated in ceramic multilayer technology employing high dielectric- constant materials. For the experimental characterisation of the balanced layout with a coplanar wafer prober, a wide-band balun was designed, which transforms a coplanar waveguide into a coplanar stripline. For the characterisation of the single-ended structures, a transition to microstrip line was used instead. For both types of antennas, measured S-parameters are presented and analysed.
