Description

Technical Field

[0001] This utility model relates to the field of antenna testing technology, specifically to a signal range detection device for antenna testing. Background Technology

[0002] Antennas are an important component in the field of communications, transmitting signals by receiving and sending radio waves. To ensure the normal operation and performance of antennas, antenna testing and inspection are necessary; each antenna requires signal strength testing after its development.

[0003] However, most existing testing devices are complex in structure, and the shielding strength is adjusted by controlling the shielding strength using wavebands. However, the devices that generate wavebands also have errors when emitting interference wavebands. These errors, when superimposed on the testing device, will lead to a further decrease in testing accuracy. Therefore, they do not meet the existing requirements. To address this, we propose a signal range detection device for antenna testing. Utility Model Content
