摘要： A transmission line comprising a multi-layer dielectric slab structure including: a dielectric substrate layer (30) having a thickness d.sub.s and permittivity .epsilon..sub.s ; a conductive ground plane (31) on the bottom surface of the dielectric substrate layer (30); a dielectric guiding layer (32) having a thickness h and permittivity .epsilon..sub.g, where .epsilon..sub.g >.epsilon..sub.s, attached to the top surface of dielectric substrate layer (30); at least one elongated and relatively narrow dielectric loading strip layer (33) having a width W, thickness d.sub.1, and permittivity .epsilon..sub.1, where .epsilon..sub.g >.epsilon..sub.1, attached to the top surface of the dielectric guiding layer (32); and a conductive coating (34) on the top surface of the dielectric loading strip layer (32). Such a structure permits single mode propagation over a relatively wide frequency band. Radiation losses due to coupling of the desired mode to the substrate modes and the conductors are furthermore reduced and the polarization of the dominant mode is such as to render said structure relatively insensitive to small deviations from parallelism among the different interfaces. This invention is directed to antenna structures formed from this type of multi-layer dielectric slab structure.

摘要： A calibration procedure for vector network analyzers utilizing a known standard, an unknown standard and a pair of offsets bearing a known length ratio (2:1) between them whereby measurements taken on the standards and their combinations with the offsets result in self-verifying redundant equations which furnish: (1) error terms according to well-known flow graph models, (2) the reflection of the unknown standard, (3) the transmission factor of the waveguiding medium from which the offsets are realized regardless of the waveguide's loss or dispersion, and (4) a figure of merit (corruption coefficient) for the quality of the acquired raw data without the necessity for computing the error terms, connecting verification standards or otherwise completing the calibration process.
