<p>A microwave dielectric resonator, e.g. in a microwave filter or microstrip circuit, is fixed between two polymeric layers of low dielectric constant which are heat bonded to provide a rugged assembly introducing minimal loss. When the layers are non-heat meltable, e.g. PTFE, they may be bonded by an intermediate layer of low melting point polymeric material of low dielectric loss, e.g. a copolymer of tetraflouroethylene.</p> |
