Abstract
For wireless high-data-rate applications, channel sounding, and radar sensors, the unlicensed frequency band around 60 GHz is of relevant commercial interest. Currently, there is enormous progress in the field of integrating 60 GHz technology in compact systems using multilayer technology and reducing costs for mass production. For full channel characterization, but also for consumer applications, dualpolarized frontends offer many advantages for enhancement of polarization mismatch and increasing data rates. In this paper we address the design, successful implementation, and application of two dual-polarized (DP) frontend solutions using the low-temperature co-fired ceramic (LTCC) technology. These DP frontends exhibit advantageous technical properties for practical implementation, e.g., up to 9 GHz bandwidth at the 60 GHz band, low cross-talk between two channel and good heat dissipation in approximately 20 x 40 mm.
