A slot antenna (10) includes two annular conductors (12, 14) separated by a slot (20). A shorting post (18) connects the annular conductors to each other at some point along the slot. The slot may have at least one serrated edge. The slot antenna can be made, e.g., by affixing conductive tape to a flexible substrate, photoetching a pattern in the copper-clad surface of a flexible substrate, or machining material from a conductive tubing.
