General low-frequency antenna design has a the larger coil and it needs for secondary processing combined with PCB. We use high-frequency antenna with circuit design to produce the effect of low-frequency antenna. Not only eliminates low-frequency antenna coil volume, but also reduce manufacturing costs and improve product yield

1.The communication distance of LF: 3m 2. The communication distance of UHF: 10m.

This technology can be applied in addition to 125KHz and 433MHz antenna combination, because the antenna design and measurement process specifications, so can be quickly applied to other high-frequency antenna design such as car keyless system.

To assist the domestic vehicle industry, motorcycle industry, system manufacturers to develop vehicle key system, can reduce costs and improve yield rate, and can assist the industry to build dual-band antenna design technology.
