Abstract
An antenna comprises a planar radiating structure, a ground plane and a feed structure. The radiation structure comprises a plurality of slots arranged symmetrically in concentric rings around an inner portion of the radiating structure. The slots are arranged to create a meandering current path on the radiating structure. The antenna produces an omnidirectional, monopole-like radiation field, and is relatively small with relatively high performance making it suitable for use in a wide variety of applications including those with challenging environments.
