Research Service :

ETC has cooperated with the Communication Research Labs (ICR) of Industrial Technology Research Institute (ITRI) to research and develop antenna and key components for a long time. Now we have the capability of doing design and, due to the reputation accumulated over a period of time, we expect to render the services for wireless communication industry.

The achievements of our object at present are as follows :
EMC Measurement Antenna Base Station Antenna UWB Filter

Dual-Polarization WiMAX Base station Antenna has been complete and rolled out. It is available for ordering now.

Low Temperature Co-fired Ceramic, LTCC Filter has been complete and rolled out. It is available for ordering or ODM now.

Our WiMAX base station antennas are optimized by geometric theory and constructed by matrix design. After a thorough analyzing and research about antenna theory and structure design, we use simulate software to support our design. This antenna can operated in 2.49~2.69GHz with VSWR under 1.5 and well radiation efficiency.

Our UWB filter is a low loss, high Q value and heat dissipation material connected with broadband circuits, which reduced the usage of lump elements with self-resonance effect to optimize the performance. While arranging circuits, we use the duel mode ring type band-pass filter to adapt the size and the specification. Because at the feed-in point used the high pass capacitor to replace the 50£[ ring resonator, it can obtain the better cut of low frequency response.
