Summary: | The application provides an antenna test method and device. The test device comprises a probe array used for setting an amplitude and a phase to enable emitted signals to be in a preset frequency bandrange and form planar waves in accordance with a test requirement in a specified silent zone, and receiving and emitting the signals during the test; and a signal processing unit used for performingpower control, signal synthesis and signal filtering processing on the signals received by the probe array, and outputting a processing result to a test instrument to test a radio frequency index of an antenna. According to the scheme, the test capability of a far field and a compact field can be realized in a short distance with low cost.
本申请提供了一种天线测试方法和设备,该测试设备包括:探头阵列,用于设置幅度和相位使发射的信号在预设频带范围内,以及指定的静区内形成符合测试要求的平面波;并在测试时,接收和发射信号;信号处理单元,用于将所述探头阵列接收的信号进行功率控制、信号合成和信号滤波处理,并将处理结果输出值测试仪表以测试天线的射频指标。该方案能够在较近的距离和较低的成本下,实现远场和紧缩场的测试能力。 |
