Abstract
Provided is an isolation antenna for a repeater which can acquire high isolation by using loop and dipole antennas, which are positioned in opposite directions to each other based on a shielding means, in a unidirectional repeater generally used in broadcasting or wireless communications even though transmitting antenna/receiving antennas having a co-channel are set up closely to each other. The transmitting/receiving isolation antenna includes: a shielding means including an electric conductor; a first antenna of a dipole antenna type in one side of the shielding means; and a second antenna of a loop antenna type in an opposite side of the shielding means where the first antenna is positioned.
