Abstract
Provided is an H-type monopole isolation antenna. The antenna provides an H-type monopole isolation antenna which can gain a high bi-directional transmitting/receiving isolation between a transmitting antenna and a receiving antenna of co-channel/co-polarization by including an antenna symmetrically positioned in right/left sides based on a covering means. A transmitting/receiving isolation antenna for maintaining high isolation between a transmitting signal and a receiving signal includes a cover which includes a conductor; and first and second antennas which are bisymmetrically positioned in right and left parts of the covering means and separately operated as a transmitting antenna or a receiving antenna. The antenna is used in a co-channel bi-direction repeater system.
