Abstract

Eine Sende- bzw. Empfangsantenne, insbesondere für den Kurz- bzw. Mittelwellenbereich, bestehend aus einem vertikalen Leiterabschnitt (l0) mit einer kapazitiven Kopplung gegenüber Erde im oberen Bereich (l3) und aus mindestens einem weiteren Leiterabschnitt (l2, 22), wobei die Leiterabschnitte (l0, l2, 22) einen nicht geschlossenen Rahmen bilden, der eine Fläche (9) umgibt, und der Anschluß von dem zweiten Leiterabschnitt (l2) und ggf. weiteren Leiterabschnitten (22) an dem jeweils vorhergehenden Leiterabschnitt (l0, l2) so ausgeführt ist, daß ein freies Endstück (l3, 23) dieses vorhergehenden Leiterabschnittes gebildet ist, wobei das freie Endstück (l3, 23) bzw. die freien Endstücke die kapazitive Kopplung bzw. weitere kapazitive Kopplungen bildet bzw. bilden. Die Anordnung ist so getroffen, daß vom ersten (l0) bzw. von jedem weiteren Leiterabschnitt (l2) jeweils nur ein Leiterabschnitt (l2, 22) ausgeht. Die Antenne bringt mehrere Vorteile, sie ist u.a. sehr breitbandig, durchstimmbar und weist einen hohen Wirkungsgrad und Strahlungswiderstand auf. A transmitting or receiving antenna, especially for the Short or medium wave range, consisting of a vertical conductor section (l0) with a capacitive Coupling to earth in the upper area (l3) and off at least one further conductor section (l2, 22), the conductor sections (l0, l2, 22) not one form a closed frame which surrounds a surface (9), and the connection of the second conductor section (l2) and possibly further conductor sections (22) on the respective previous conductor section (l0, l2) so executed is that a free end piece (l3, 23) this previous conductor section is formed, the free end piece (l3, 23) or the free end pieces capacitive coupling or further capacitive couplings forms or form. The arrangement is such that from the first (l0) or from every further conductor section (l2) only one conductor section (l2, 22) goes out. The antenna has several advantages, among other things it is very broadband, tunable and has a high Efficiency and radiation resistance.
