ABSTRACT:
An antenna apparatus for a folder type mobile phone, wherein a first antenna is installed in a main body of the folder type mobile phone, and a second antenna is installed in the folder. The folder type mobile phone installs a main antenna apparatus in the main body, and an antenna apparatus for maximizing the diversity effect in the folder. As a result, it becomes more convenient to carry the folder type mobile phone based on the diversity mode, while securing a broader separation distance between two antennas at the same time.
