Abstract

A small planar antenna combined with a printed circuit board (PCB). The planar antenna includes: a dielectric layer with a predetermined thickness; first and second ground layers formed on top and bottom surfaces of the dielectric layer, respectively, corresponding to each other; and a first antenna unit which extends from a side of each of the respective first and the second ground layers, for radiating a first polarized wave with the application of current. A second antenna unit extends from a side of each of the respective first and second ground layers, for radiating a second polarized wave orthogonal to the first polarized wave with the application of current. A feeding stripline is installed between the first and second antenna units, in the dielectric layer, for applying the current to the first and second antenna units, wherein the first and second polarized waves can be separately radiated.
