1. An antenna device for 5G mobile communication base station and repeater, the antenna device comprising:
a receiving antenna part 210;
a transmitting antenna part 220 separated from the receiving antenna part 210;
a first low-noise amplifier 217-1 connected to an output terminal of the receiving antenna part 210;
a phase shifter 221, 222 connected to the input terminal of the transmitting antenna part 220;
a transmission signal canceller 231, 232 which is an interference canceling synthesizer connected to the first low-noise amplifier 217-1 and the phase shifters 221, 222, respectively; and
a band-pass filter 233, 234 of usable frequency bands connected to each of the transmission signal canceller 231, 232,
wherein the receiving antenna part 210 comprises a plurality of receiving radiation element Rm,
the transmitting antenna part 220 comprises a plurality of transmitting radiation elements Tn,
the antenna device further includes
a second low-noise amplifier 217-2, a switch part 217-3 and a power control panel 240,
wherein when the first low-noise amplifier 217-1 is damaged, the first low-noise amplifier 217-1 is switched to the second low-noise amplifier 217-2 by the switch part 217-3, and the power control panel 240 notifies the operating room of whether the first low-noise amplifier 217-1 is damaged.
