- TESCOM’s Antenna couplers can measure the near field wave of DUT in a shield box of TESCOM without using any physical RF connector. TESCOM’s Antenna couplers can be used for current and future communication technologies, such as GSM, WCDMA, WiMAX, LTE, GNSS, Bluetooth, Wi-Fi, with its wide frequency range from 80 MHz to 6 GHz; therefore, it is possible to be used for multi frequency bands DUT as well. |
- Jul 14, 2014 · The two halfs of the antenna are connected in the middle like a "U". Its covered in the shown picture.
