The invention discloses a compact dual-circularly-polarized common-caliber transmitting and receiving simultaneous antenna. The antenna comprises a dielectric substrate, a coaxial probe and a coaxial line. According to the invention, the rectangular groove is utilized to enable the two coaxial ports to emit right-hand circular polarization and receive left-hand circular polarization, but the coupling between the emitting port and the receiving port is very strong at the moment, and the arc-shaped groove is utilized to change the phase by analyzing the electric field and changing the phase relation of the orthogonal electric field, so that the coupling between the emitting port and the receiving port is very strong. The energy addition of the orthogonal electric field is changed into subtraction, so that the coupling of the transmitting antenna and the receiving antenna is reduced. The transmitting function and the receiving function of the dual-circularly-polarized common-caliber transmitting and receiving si
