    • Provided is an antenna system with high isolation. The high-isolation antenna has transmission ports of a transmission antenna and reception ports of a reception antenna highly isolated from each other by using quadrature hybrid couplers. The antenna system includes: a transmission antenna having two feed points for transmitting signals; a reception antenna having two feed points for receiving signals; a transmission hybrid coupler which is connected to the two feed points of the transmission antenna and transmits transmission signals which have a phase difference of 90° with each other; and a reception hybrid coupler which is connected to the two feed points of the reception antenna and receives reception signals which have a phase difference of 90° with each other. The signals leaking from the two feed points of the transmission antenna to the two feed points of the reception antenna are offset.
    • 提供了具有高隔离度的天线系统。 高隔离天线具有通过使用正交混合耦合器彼此高度隔离的发送天线和接收天线的接收端口的传输端口。 天线系统包括:发射天线,具有用于发射信号的两个馈电点; 具有用于接收信号的两个馈送点的接收天线; 传输混合耦合器,其连接到发射天线的两个馈电点,并发射相位差为90°的发射信号; 以及接收混合耦合器,其连接到接收天线的两个馈电点,并接收彼此具有90°的相位差的接收信号。 从发送天线的两个馈电点泄漏到接收天线的两个馈电点的信号被偏移。
