The disclosed antenna includes: a dielectric substrate; a feed line for feeding RF signals that is formed on an upper portion of the dielectric substrate and has a linear form; a multiple number of open stubs that extend at particular angles from the feed line and have linear forms with particular widths; a matching element for adjusting impedance matching that is joined to an end of the feed line; and a ground formed on a lower portion of the dielectric substrate, where the open stubs operate as radiators, and at least one of the open stubs has a different length for adjusting a radiation signal intensity of each open stub. The disclosed antenna can be manufactured with a simple structure and a compact size.
