Claim 10:
11. An antenna module provided in an electronic device, the antenna module comprising:
a monopole antenna disposed inside a first substrate, and configured to radiate a first signal in the direction of a side surface of the first substrate, the first signal having a first polarization;
a dipole antenna disposed on a second substrate which is disposed perpendicular to the first substrate, and configured to radiate a second signal in the direction of the side surface of the first substrate, the second signal having a second polarization perpendicular to the first polarization;
a dielectric package disposed on a rear of the first substrate, and formed to surround a radio frequency integrated circuit (RFIC) operatively coupled to the monopole antenna and the dipole antenna; and
a baseband processor operatively coupled to the RFIC and configured to control the RFIC,
wherein the monopole antenna includes:
a radiator formed in a metal pattern having a predetermined width and length;
a first matching portion connected to the radiator and formed in a metal pattern on an end of the second substrate;
a second matching portion formed in a metal pattern on an end of a side surface of the dielectric package attached to the first substrate; and
a feeding portion connected to the second matching portion and configured to apply a signal to the radiator through the first matching portion and the second matching portion,
wherein the first matching portion and the second matching portion are spaced apart from each other by a predetermined gap between the dielectric package and the second substrate,
wherein the dipole antenna is formed as a first array antenna including a plurality of dipole antenna elements spaced at predetermined intervals,
wherein the monopole antenna is formed as a second array antenna including a plurality of monopole antenna elements spaced at predetermined intervals,
wherein the baseband processor controls the RFIC so as to radiate a horizontal polarization signal through the first array antenna and to radiate a vertical polarization signal through the second array antenna.
