TL;DR: This work assesses the reduction in the cumulative probability of losses caused by these two effects through spatial diversity by using a multiaperture receiver configuration to estimate the probability distributions of power fades.
Abstract: To estimate the probability distributions of power fades, we consider two basic types of disturbance in electromagnetic wave propagation through atmospheric turbulence: wave-front intensity fluctuations and wave-front distortion. We assess the reduction in the cumulative probability of losses caused by these two effects through spatial diversity by using a multiaperture receiver configuration. Degradations in receiver performance are determined with fractal techniques used to simulate the turbulence-induced wave-front phase distortion, and a log normal model is assumed for the collected power fluctuations.

TL;DR: In this article, a transition from microstrip into the even mode coupled-slot fin-line was developed for the Ka band, particularly over 28 to 40 GHz, with levels of performance achieved similar to that reported in the above paper.
Abstract: For original paper see D.B.Sillars, Proc. Inst. Elec. Eng., vol.134, pt.H, no.3, pp.229-33 (1987). The authors of the above letter may be interested in work that was previously carried out to excite both odd and even modes in coupled-slot fin-line circuits. A similar transition from microstrip into the even mode coupled-slot fin-line to that proposed in the above letter was developed for Ka band, particularly over 28 to 40 GHz, with levels of performance achieved similar to that reported in the above letter. This transition was primarily developed as part of an investigation into the nonreciprocal effects of loading coupled-slot fin-line circuits with longitudinally magnetized ferrite slabs.
