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.

Miniature antenna with omnidirectional radiation field

An antenna for a body-centric wireless communication system comprises first and second radiating structures between which is located a ground plane and a feed structure. The feed structure comprises a feed line extending between the first radiating structure and the ground plane, and a slot formed in the ground plane. A pair of shorting posts connects the first radiating structure to the ground plane. The antenna is capable of simultaneously generating in-body radiation, on-body radiation and off-body radiation in the same frequency band.
