A calibration network, a filter and a radio frequency connector are integrated on a PCB of the calibration module. Thus, the calibration module has both signal calibration and filtering functions. Therefore, the MASSIVE MIMO antenna does not require an external filter during use. Moreover, the calibration network, the filter, and the radio frequency connector are integrated through the PCB, so that the structure of the calibration module is more compact. Therefore, the degree of miniaturization of the above-mentioned MASSIVE MIMO antenna is higher, so that the above-mentioned communication base station is miniaturized. In addition, since the filter and the calibration network are designed as integrated, the matching performance of electrical parameters of two cascaded components can be fully considered in the design. Therefore, the matching performance of electrical parameters can be optimized as much as possible so as to achieve an optimal interconnection design of filter performance and antenna performance.
