Antennas and methods for controlling antennas for producing electromagnetic radiation in a desired direction over a wide range of wavelengths. A current distribution is controlled in one or more conductive radiating elements of an antenna to form, at every wavelength within a pattern wavelength range, an antenna radiation pattern having a peak in a direction substantially orthogonal to a length of an elongated conductive radiating element or elements. By careful control of the current distribution, the pattern wavelength range is made exceptionally broad. In the case of a dipole antenna, the pattern wavelength can range from about &#x2153;l to at least about 8l, where l is an approximate combined length of a pair of elongated elements forming a dipole antenna. Alternatively, in the case of a monopole antenna, the pattern wavelength range can extend from about &#x2159;l to at least about 4l, where l is an approximate overall length of the monopole antenna.

Multiband dismount antenna

A fastening device () for releasably securing an antenna assembly () on at least one garment () of a user () is provided. The antenna assembly () is part of a portable communication system () which includes a portable communication device () that is also worn on the garment () of the user (). The fastening device () is comprised of a body portion () and an elongated receiver portion (). The elongated receiver portion () defines an elongated channel () and a pair of resilient undulations () which define an elongated opening (). The pair of resilient undulations () serve to guide a segment () of the antenna assembly () through the elongated opening () and into the elongated channel (). Once the segment () is urged into the elongated channel (), the undulations () return to the normal position thereby securing the segment () in the elongated channel (). The fastening device () is attached to a loop () on the at least one garment () of the user () with straps using hook and loop fasteners, a pair of slide keeper clips, or a carabineer clip.

Body-worn antenna fastening device and method

Antenna assemblyto be worn by a user includes a low-band dipole antenna () and at least one high band dipole antenna (). The high-band dipole antenna is comprised of a high-band dipole feed () interposed at a location along a length of a low-band dipole element (). The high-band dipole feed divides the first low-band dipole element into a first high-band dipole element () and a second high-band dipole element (). One of the high-band dipole elements () is formed as a flexible electrically conductive sleeve. An RF control device () is provided for selectively directing RF energy in a high-band to the high-band dipole feed (), and for selectively directing RF energy in a low-band to the low-band dipole feed (). A transmission line () extends from the RF control device () to the high-band dipole feed ().

Multiband antenna system for body-worn and dismount applications

An antenna system is provided including a rapidly expandable-collapsible housing which mounts two sections of fabric material each having an array of antenna elements formed of electrically conductive material such as copper thread embedded in the fabric sections. The fabric sections are movable between the expanded and collapsed positions with the housing and are located in different planes.
