Abstract
Provided is a transmitting/receiving isolation antenna that can perform wireless bi-directional communication in the co-channel, co-polarization and co-time by acquiring high isolation from transmitting and receiving antennas having co-time, co-channel and co-polarization and set up adjacently. The isolation antenna includes a first antenna; second and third antennas symmetrically positioned in the same distance from the first antenna; a shielding unit symmetrically positioned between the first and second antennas, and between the first and third antennas; and a signal removing unit for removing a signal transmitted from the first antenna to the second and third antennas.
