Abstract: A method in which a User Equipment (UE) measures a downlink signal in a wireless communication system is disclosed. The method includes receiving information about a Beam Direction Pattern (BDP) of the downlink signal and measuring the downlink signal based on the information about the BDP. The information about the BDP includes an index of a subframe in which the downlink signal is to be transmitted using a specific BDP and includes an identifier (ID) of the specific BDP. The BDP of the downlink signal is switched according to the subframe index based on the information about the BDP.

Abstract: A broadband patch antenna comprises a substrate, a ground plate attached to one surface of the substrate, a radiation plate attached to the other surface of the substrate opposite the one surface of the substrate, and a feed line attached to the other surface of the substrate and having one end connected to the radiation plate. The feed line comprises a first line and a second line. The ground plate has the shape of capital “L” having a first groove, a second groove, and a third groove, and may not comprise a portion corresponding to the radiation plate. The first groove is positioned at a first portion which corresponds to a connection portion between the first line and the radiation plate, the second groove is positioned at a second portion which corresponds to a connection portion between the second line and the radiation plate, and the third groove may be positioned so as to be spaced apart from the first groove and the second groove.
