<p>An antenna assembly 1, suitable for being carried by a person, comprises: a driven element 2 mounted on a support 4 which is configurable between a deployed operational arrangement and a collapsed stowed arrangement and where a mechanism, activated by the person, changes the configuration between the deployed and collapsed conditions. Also disclosed is an antenna comprising at least one elongate driven element 2 which is attached to a support 4 in a releasable manner such that it extends in a radial direction relative to the support. The support 4 may be a central elongate column member with multiple elongate driven and ground members 2, 3 attached in a hinged, and possibly sliding ring, arrangement to the support 4. The driven and ground members 2, 3 may be arranged to collapse into a housing 7 such that they are adjacent and aligned with the support 4 in a compact arrangement and to extend in respective planes in a radial manner relative to the support 4, in a deployed condition sitting on top of the housing 7. The antenna 1A may further include means to bias the antenna towards its deployed condition. The antenna 1A may be used by the military for quick and simple operation and it may be mounted on a backpack, on the ground or on a vehicle.</p> |
