    Abstract: Provided is a parallel mechanism consisting of: a first module including a first plate having a first hollow formed therein; a second module disposed to be spaced apart from the first module, and including a second plate having a second hollow formed therein; and a power transmission unit provided in a space between the first and second modules, and including a third plate connecting the first and second modules in parallel, wherein the first and second modules form a symmetrical structure on the basis of the power transmission unit, a first range of motion in the first module is amplified, by means of the symmetrical structure, to a second range of motion that is wider than the first range of motion in the second module, a working space is formed in a space communicating with the first and second hollows, and the third plate is provided outside the working space.

    Abstract: A wearable antenna comprises: an upper substrate made of a solid material; an inner open ring radiator formed on an upper surface of the upper substrate and having a first slit formed therein; an outer open ring radiator formed in a ring shape having the same center as the inner open ring radiator and having a larger radius on the upper surface, and having a second slit formed therein to open a partial area; a feeding portion formed on a lower surface of the upper substrate and transmitting a feed signal applied from an input port to each of the two open ring radiators through two vias penetrating the upper substrate; a lower substrate spaced apart from the lower surface of the upper substrate by a predetermined distance and made of a flexible material; and a ground plane formed on a lower surface of the lower substrate.
