Description

Примен емые в насто щее врем  в установках дл  однонаправленного приема или в радиогониометрах приемные рамки представл ют собой системы с мен ющимс  в широких пределах по диапазону сопротивлением , особенно, если диапазон обслуживаемых рамкой частот достаточно велик. Сильные колебани  сопротивлени  затрудн ют настройку приемника и заставл ют разбивать диапазон на поддиапазоны, увеличива  число антенных устройств. Кроме того, по этим же причинам рамки должны ставитьс  возможно ближе к приемному зданию, так как длинна  соединительна  лини  между рамкой и приемником может дать такое сопротивление на зажимах, при котором настройка входа приемника не сможет быть осуществлена. Дл  устранени  указанных недостатков , согласно насто щему изобретению , предлагаетс  включить в среднюю точку рамки последовательно сопротивление, равное ее волновому сопротивлению (пор дка 1000 ом). Схема такого включени  показана на фиг. 1 и 2. Включение по схеме фиг. 1 сохран ет направленную характеристику рамки в виде восьмерки лишь дл  горизонтального направлени , что в больш инстве случаев вполне достаточно. Включение по схеме фиг. 2 позвол ет получить восьмерочную характеристику дл  любых направлений прихода волны в вертикальной плоскости, тех же, как и дл  обычной рамки.The presently used in installations for unidirectional reception or in radiogonimeters, the receiving frames are systems with varying resistance over a range, especially if the range of frequencies served by the frame is large enough. The large fluctuations in impedance make it difficult to tune the receiver and cause the band to be divided into sub-bands, increasing the number of antenna devices. In addition, for the same reasons, the frames should be placed as close as possible to the receiving building, since the length of the connecting line between the frame and the receiver can give such a resistance at the terminals that the setting of the receiver input cannot be made. In order to eliminate these drawbacks, in accordance with the present invention, it is proposed to include in the midpoint of the frame a successively resistance equal to its characteristic impedance (on the order of 1000 ohms). A diagram of such an inclusion is shown in FIG. 1 and 2. Switching on according to the scheme of FIG. 1 retains the directional characteristic of the frame as a figure of eight only for the horizontal direction, which in most cases is sufficient. The inclusion according to the scheme of FIG. 2 allows to obtain an eight-dimensional characteristic for any direction of wave arrival in the vertical plane, the same as for the usual frame.

Чтобы по снить сказанное, предположим , что к зажимам рамки присоединен генератор. Тогда в рамке установитс  бегуща  волна тока. Векторы 1 фиг. 2 указывают фазу тока в проводе /, векторы 2 - фазу тока в другом проводе 2 дл  различных точек. Как видим, результирующий ток аст сто чую волну, как и в обычной рамке. Следовательно, направленна  характеристика будет та же, что и у обычной рамки. Сказанное , на основании принципа взаимности , может быть распространено и на приемные рамки.In order to remember what has been said, suppose that a generator is attached to the frame clips. Then a running current wave will be installed in the frame. Vectors 1 of FIG. 2 indicate the phase of the current in the wire /, the vectors 2 indicate the phase of the current in the other wire 2 for different points. As you can see, the resulting current as the standby wave, as in the usual frame. Therefore, the directional characteristic will be the same as that of the ordinary frame. What has been said, on the basis of the principle of reciprocity, can be extended to the receiving framework.
