In this paper，The design of a low side-lobe compressed dipole resonating at the third mode is proposed in order to solve the problem of a high side-lobe in the mode compressed dipole antenna. This paper adopts a method of loading a bent inductor on the dipole antenna to achieve a larger compression coefficient，thus the radiation interface of the reverse current is reduced. Finally，the target of designing mode compression antenna with low side-lobe and high gain is realized，which achieves a low side-lobe of -15.35 dB and a gain of 5.11 dBi. The mutual interference is reduced，and the transmission distance and speed are increased. In order to verify the validity of the simulation model，the PCB technology is used to manufacture the model and test it. The simulation results are in good agreement with the test results.
