The paper gives a review to analyse the outcomes achieved in the field of micro-strip directional couplers within 2010 – 2017. Considers design features of over twenty original or modified quadrature micro-strip directional couplers within ultrahigh (UHF) and super-high frequency (SHF) bands. The focus is on the ways to reduce overall dimensions of traditional loopback, printed and coupled couplers, enhance their use in several frequency bands, suppress higher order harmonics up to the sixth, provide broad-banding operation frequency to several octaves, change a type of the laterally-coupled coupler directionality from the counter-directional to the co-directional and trans-directional ones. The results obtained are achieved due to the following: the change of the quarter-wave line segments for their equivalent micro-strip “П”- and “T”- like structures and their combinations, the quasi-fractal topological implementation of devices, the use of composite transmission lines with the properties of meta-materials, the use of defects of various shapes in the ground plane, the samples in the signal layer of metallization, the low-pass filters in combination version of high-resistance and low-resistance lines, the use of special-form coupling apertures in a multilayer response which allows to compensate for the differences in phase lengths of the segments of connected lines for the even- and odd-order modes, thereby enabling significant improvement of coupler characteristics. The paper briefly describes coupler topologies, equivalent circuits and device layouts. Shows amplitude-frequency and phase-frequency characteristics simulated in computer-aided design systems. Also presents measuring results of the fabricated mock-ups of micro-strip directional couplers. The results obtained may be of interest to the creators of SHF devices and those involved in further investigation to seek and improve couplers of known designs.

Presently, in the territory of Russia active millimeter solar observations are under way via Bauman Moscow State Technical University (BMSTU) RT-7.5 radio telescope (Shustikov et al., 2015, Smirnova et al., 2016; Rozanov 1981; Smirnova et al., 2013; Ryzhov et al., 2014). Rozanov 1981; Smirnova et al. 2013; Рыжов и др. 2014). A radio telescope antenna of the 7.75 m diameter with its unique receiving equipment mounted for frequencies of 93 and 140 GHz, (3.2 and 2.2 mm) allows observing the Sun in the mode of tracking area, or scanning, simultaneously at two frequencies. Such observations are a source of the most valuable information on flares - the most powerful solar activity effects. It is impossible to understand a nature of the energy release mechanisms in the solar flares when there is no adequate diagnosis of physical parameters of plasma and magnetic fields. Meanwhile, sub-THz (0.1-1 THz) radio observations make it possible to diagnose the most inaccessible areas for the Sun researchers, i.e. the chromosphere. The ground-based observations in the millimeter range are rare because of high sensitivity requirements for receiving equipment and significant atmosphere disturbances, while the appropriate space projects are just under development. The paper objective is to investigate a nature of the sub-THz emission from the flare with the positive spectral tilt recorded on the RT-7.5 radio telescope on April 2, 2017. To solve this problem, we used observations in the x-ray, ultraviolet, and microwave ranges. Based on the model of the flare Machado et.al. (1980) Chromosphere, a coronal plasma contribution to the millimeter radio emission has been estimated. This approach allows us not only to take a fresh look at the results obtained earlier, but also makes it possible to diagnose in-depth the physical parameters of the flare plasma.
目前，在俄罗斯境内，通过鲍曼莫斯科国立技术大学(BMSTU) RT-7.5射电望远镜(Shustikov et al.， 2015, Smirnova et al.， 2016;Rozanov 1981;Smirnova et al.， 2013;Ryzhov et al.， 2014)。Rozanov 1981;Smirnova et al. 2013;Рыжов * др。2014)。一个直径7.75米的射电望远镜天线，其独特的接收设备安装在93和140千兆赫(3.2和2.2毫米)的频率上，可以同时在两个频率上以跟踪区域或扫描的方式观察太阳。这些观测是关于耀斑的最有价值的信息来源——耀斑是最强大的太阳活动效应。如果没有对等离子体和磁场的物理参数进行充分的诊断，就不可能理解太阳耀斑能量释放机制的本质。同时，亚太赫兹(0.1-1太赫兹)的无线电观测使太阳研究人员能够诊断出最难以接近的区域，即色球层。由于对接收设备的高灵敏度要求和明显的大气干扰，毫米范围的地面观测很少，而适当的空间项目正在开发中。本文的目的是研究2017年4月2日RT-7.5射电望远镜记录的正光谱倾斜耀斑的亚太赫兹辐射的性质。为了解决这个问题，我们在x射线、紫外线和微波范围内进行了观测。基于耀斑模型，Machado等。(1980)估计了日冕等离子体对毫米射电辐射的贡献。这种方法不仅使我们对先前获得的结果有了新的认识，而且使深入诊断耀斑等离子体的物理参数成为可能。
