An image-reject antenna having a function for intercepting an image frequency signal among signals received from an antenna is provided. The image-reject antenna includes an antenna unit which receives a wireless signal from a space or transmits a predetermined signal to a space and does not receive image noise when receiving the signal, and an impedance matching unit which removes image noise having a predetermined frequency among signals received from the antenna unit. The noise component of the image frequency that is transmitted to the subsequent circuit, can be minimized or removed by including an image-reject function when designing the antenna and the matching circuit, thereby realizing improved image-reject performances of the entire receiver. <IMAGE> |
