Portable dual-band antenna

摘要

An antenna provides two antenna elements, which are connected to one another. The second antenna element can be connected to a radio device. The first antenna element and the second antenna element together form a first antenna part. The second antenna element alone forms a second antenna part. The first antenna element comprises at least in part at least one flexible metal strip. The second antenna element comprises at least in part a flexible corrugated tube.
