Antenna detection system

Abstract

This invention discloses an antenna testing system capable of measuring an antenna under test. The antenna testing system includes a workstation, a multi-item tester, and a controller. The workstation includes a placement location for placing the antenna under test. The multi-item tester is mounted on the workstation. The multi-item tester can acquire radio frequency characteristic data, electrical impedance data, and response data through the antenna under test placed at the placement location. The controller is communicatively coupled to the multi-item tester. The controller includes a processor and a memory. The memory stores multiple instructions. When the multiple instructions are executed by the processor, the radio frequency characteristic data, electrical impedance data, and response data are sequentially acquired by the multi-item tester for testing.
