A body wearable antenna adapted to be worn against the body, comprising: a first antenna part (); and a second antenna part () insulated from the first part (); wherein the first antenna part () is adapted to be worn circumferentially around a body part (); and the second antenna part () is adapted to be worn longitudinally against a body part (). The body parts that the first antenna part () is adapted to be worn around and that the second antenna part () is adapted to be worn against maybe the same. The second antenna part () may extend circumferentially around the body part () to some extent and may extend along substantially the whole length of the body part (). The second antenna part () may comprise a plurality of radial elements () that extend away from the first antenna part ().

Body wearable antenna

In an antenna array consisting of a plurality of antennas, an antenna may behave as if its transmitted radiation emanates from a position, phase center, disposed away from the actual location. Probe antennas are used with a processor to locate the phase center of respective antennas at a selected frequency of transmission and to adjust the phase center to a desired location, thereby calibrating the antenna array for the selected frequency.
