TL;DR: In this article, a 50/spl Omega/suspended stripline with a probe was built and tested at 30 GHz with a return loss better than 35 dB and matching was obtained between 28.8 and 32.6 GHz.
Abstract: A launcher for coupling a 50-/spl Omega/ suspended stripline to a waveguide by means of a probe has been built and tested at 30 GHz. Matching has been obtained between 28.8 and 32.6 GHz with a return loss better than 35 dB. The launcher can be fabricated as an integral part of the stripline components.

TL;DR: In this paper, a system is presented which provides a decade improvement in voltage reflection coefficient measurement accuracy over the range of 0 to 50 dB return loss, which separates the unknown from the error signals.
Abstract: A system is presented which provides a decade improvement in voltage reflection coefficient measurement accuracy over the range of 0 to 50 dB return loss. The technique separates the unknown from the error signals. Two methods using a combination of old and new techniques are presented Error Averaging and Magnified Swept Sensor. The basic ingredients are precision airline and directional bridge. A mathematical review of the old and the new reflectometer methods will be included.

TL;DR: In this article, the Fourier coefficients of the return loss function were determined for the minimum phase reflection coefficient without any factorization process or synthesis procedure, which can be extended directly to the design of mixed lumped-distributed transmission line networks.
Abstract: The conventional method of designing stepped impedance transmission line networks from gain functions requires the use of a factorization process to obtain a passive input impedance, and then the application of Richards Theorem to determine the element values. A new technique is presented based upon the determination of the Fourier coefficients of the return loss function from which the element values may be obtained immediately for the minimum phase reflection coefficient without any factorization process or synthesis procedure. It is believed that this new technique may be extended directly to the design of mixed lumped-distributed transmission line networks whereas the conventional approach may not.
