Abstract
Official abstract text for this publication.
A foldable log-periodic antenna includes a feed line, one or more transmitting elements for transmitting and/or receiving electromagnetic signals, one or more supporting elements for holding the transmitting elements, and one or more elements for producing a tensile stress on the transmitting elements. One of the a transmitting elements is connected to one of the supporting elements and to the feed line, and with one supporting element is connected to the feed line via an articulated joint apparatus, such that the antenna can be moved from a transport position to an operating position and vice versa. The one or more elements for producing a tensile stress on the transmitting elements is a flexible tube, and can have an internal pressure applied to them and are connected to the supporting elements for holding the transmitting elements.
First claim
Opening claim text (preview).
