Current 5G communication devices have a huge demand in high resolutiondensity of metal conducting wires in electronics ( 40 μm line width/line spacing), which cannot be achieved by conventional screen printing (100 μm). Our group cooperated with Ample Technology to develop a new-generation silver conductive paste which enables photolithographyachieves outstanding line resolution (5 μm width/13 μm spacing). The paste is simple to useperforms comparable of those of major European, AmericanJapanese manufacturers.

The major cost of conventional RFID tags comes from a microchip. To reduce the start-up cost, we develop a chipless RFID system that eliminates the use of the chip. This research organize the real-world issues of chipless RFID into four subjects, including the design of chipless tags, chipless RFID readers, reader signal processing,wireless propagation channel. We successfully integrate the four topics, developing a calibration-free, orientation-insensitive,high-capacity chipless RFID system with multi-tag detection capability.

iTech has developed an Innovative Wireless Positioning&Tracking System. iShield can simultaneously detect drones & operators. iPosition tracks thousands of targets indoor. iFollow is an auto-following function for smart droids.

A coplanar-waveguide defected ground structure is invented for signal filtering of communication systems. The performance of the coplanar-waveguide defected ground structure can be easily determined by the design of the simple ground defects. It demonstrates excellent passband stopband, leakage wave,slow wave characteristics.
