DUAL RESONANCE ANTENNA FOR WIRELESS LOCAL AREA NETWORK

摘要

PURPOSE: A dual resonance antenna is provided to use the antenna in systems using different frequencies by permitting the antenna to be simultaneously used in a dual frequency band of a wireless LAN system. CONSTITUTION: A dual resonance antenna comprises a first monopole antenna(510) arranged in the center of an antenna, and which has a length of 1/4 of wavelength of a substantially low frequency; and a plurality of second monopole antennas(520) arranged around the first monopole antenna, wherein each of the second monopole antennas has a length of 1/4 of wavelength of a substantially high frequency.
