Abstract
Disclosed herein are a method for eliminating passive intermodulation distortion (PIMD) and an antenna apparatus using the same. According to an embodiment, the antenna apparatus includes a main antenna used for transmission and reception of an RF signal; an auxiliary antenna used for reception of an RF signal; and a passive intermodulation distortion (PIMD) eliminator configured to calculate PIMD contained in a received signal of the main antenna using a received signal of the auxiliary antenna, and to eliminate the calculated PIMD from the received signal of the main antenna.
