APPARATUS FOR MULTIPLE ANTENNAS IN WIRELESS COMMUNICATION SYSTEM

摘要

PURPOSE: An apparatus for multiple antennas in a wireless communication system is provided to effectively lower the coupling coefficient between antennas by connecting the antennas with a capacitive neutralization line. CONSTITUTION: In an apparatus for multiple antennas in a wireless communication system, a first antenna(901) and a second antenna(902) have an inverted - F antenna structure. The first and second antenna receives a signal through a feeding unit. The connection line between the antennas and feeding units is widened in antenna direction. The capacitive neutralization line(914) indirectly connects the antennas using a physically separated line The capacitive neutralization line includes a capacitance matching stub to compensate capacitance mismatch.
