The invention proposes a technique to enable a wireless link for wearable wireless device. The technique includes a three dimensional (3D) folded flexible slot antenna design of small size for the wearable wireless devices. The antenna is small in size with low profile and worn on hand wrist or some other places on a human body. The antenna maintains radiation efficiency while being loaded on the human body and radiation pattern is close to Omni direction. The antenna operates around certain gigahertz (GHz) to satisfy all requirements, which include small size, low profile and worn on hand or body part in order to enable long-range wireless transmission. The antenna slot includes slotted ground plane, supported by a flexible thin substrate of kapton. Under the substrate is a microstrip feed line to excite the slot and a matching hub. A flexible dielectric strip of kapton, which is loaded on top of the slot, supports a capacitive metal strip.
