Antenna Tuning and Optimization Service

We are pleased to help customers with their antenna designs.

Our anechoic chamber allows us to respond quickly to customer requests.



Active OTA Cellular Band Tester

It is possible to quickly ascertain the OTA measurement by using both the reverberation chamber and the communication tester.
It is based on the RF transmit and receive tests of various communication methods for 3GPP.
The latest communication method: Carrier Aggregation ⇒ 2CA / 2x2 MIMO is available.

Reverberation Test System (BLUETEST AB)

The reverberation chamber enables quick testing of radiation efficiency of small antennas for multi-path enviroments such as W-CDMA, GSM, LTE, Bluetooth and W-LAN.

This is an alternative to the conventional evaluation method of integration of the three-dimensional radiation pattern data measured in an anechoic chamber.
The system is particularly suitable to measure terminals in the immediate vicinity of a head phantom in order to mimic the effect of a human body.

Passive diversity
Passive Multi-Input Multi-Output (MIMO)
Frequency range 650MHz~6GHz
RF shielding > 100dB
Accuracy 0.3dB (std)
Repeatability 0.1dB (std)
