Abstract:
1. A planar antenna assembly, the assembly comprising: an antenna which is disposed in parallel with an installation surface, and comprising a first radiation element and a second radiation element, wherein the first radiation element is disposed on a first surface of a printed circuit board, and wherein the second radiation element is disposed on a second, opposite surface of the printed circuit board; a planar lower cover which is disposed in a lower portion of the antenna so that the antenna is fixed and connected with the planar lower cover; and a planar upper cover which is disposed in an upper portion of the antenna, is fastened to the lower cover, and covers the antenna to provide an installation space for the antenna, wherein each of the first and second radiation elements is a half-wavelength dipole which is copper-foil printed on the corresponding first or second surface of the printed circuit board, wherein, when the first radiation element on the first surface is projected onto the second surface, or, when the second radiation element on the second surface is projected onto the first surface, the first and second radiation elements do not mutually share a radiation surface.
