Abstract:
1. A method of mass producing a transceiver with a high frequency antenna having a low temperature co-fired ceramic substrate, said method comprising the steps of: (a) providing one or more layers of a low k thick film dielectric tape in contact with each other, each having dielectric constant in the range of 3.5 to 6.5 and comprising, based on solids: (a) 40-80 weight percent glass composition; (b) 20-60 weight percent ceramic oxide; dispersed in a solution of (c) organic polymeric binder; to form an LTCC low k layered structure, (b) contacting said low k layered structure with an LTCC high k structure made from one or more layers of a high k material, to form an assembly having an exposed low k surface and an exposed high k surface, (c) providing a patch antenna pattern on the exposed low k surface, (d) processing the assembly to form a low temperature co-fired ceramic structure, and (e) providing chip circuitry on the exposed high k surface.
