Abstract
The invention relates to a microwave antenna having at least one tubular portion with a central axis, and magnets which are located within the tubular portion along the central axis. The magnets generate a magnetic field in the vicinity of the antenna, with each end of each magnet facing an end having the same polarity of an immediately adjacent magnet. This type of antenna is used in the manufacture of microtips on large surfaces.
