MHMICs on Ceramic Substrate for Advanced Millimeter Wave Systems Bouraima Boukari, Djilali Hammou, Emilia Moldovan, Ke Wu*, Renato G. Bosisio*, and Serioja O. Tatu Institut national de la recherche scientifique INRS-EMT, and École Polytechnique*, Montréal, CANADA ABSTRACT This paper presents the simulation fabrication and measurement results of several new passive millimeter wave circuits integrated on a thin ceramic substrate, having a relative permittivity of 9.9 and a thickness of 127 μm. The work is focused on the design and experimental characterization of a Wilkinson power divider, a 90° ring hybrid coupler, a rate-race coupler, and several six-port architectures. Experimental results show the wideband characteristics over the V and W millimeter wave bands, allowing therefore their use as circuits for high data-rate wireless communication systems and radar sensors.

CONCLUSIONS New millimeter wave passive MHMICs, including different six-port architectures are designed and fabricated in microstrip technology.  Simulation and measurement results show that the proposed circuits are wideband components which can be used for V and W band applications, such as high data-rate communications and radar sensors. For example, multi-carrier ultra wideband communication systems, such as 4 QPSK modulated carriers at 500 Mb/s per carrier, are currently under consideration. In addition, for radar applications, homodyne and heterodyne FMCW radar sensors using the proposed six-port circuits are also investigated.
