Diversity antenna apparatus for portable wireless terminal

A diversity antenna apparatus for a portable wireless terminal is provided with a main body having a main board installed therein and a folder electrically connected to the main board by a flexible printed data cable so as to be rotatably opened from and closed into the main body. The antenna apparatus includes a first antenna protruding from first side of an upper end of the main body so as to perform a transmitting and receiving function and a second antenna installed on a second side of an upper end of the main board and separated from the first antenna so as to perform a diversity receiving function. The diversity antenna is separated from the antenna apparatus by a sufficient distance, thereby improving a diversity effect. Further, the diversity antenna is installed within a space in the main body of the terminal, thereby not requiring a structural change and being easily installed in the portable wireless terminal.
