High-gain antenna, long-distance identification, sensitive sensing

The circularly polarized antenna increases the signal reception range and does not have many requirements on the direction of the tag. The antenna radiation range is wider and the sensitivity is higher. The reading distance of the linearly polarized antenna is relatively long, but the directionality is obvious. The reading distance varies greatly depending on the direction of the tag.

Forward sector-shaped card reading area, the center point of the antenna has the farthest reading distance

The flat panel antenna is a directional card reader, and its range is spread in a fan-shaped (approximately 35-70°) area on the front. The center point of the card reader has the farthest reading distance, and the card reading distance and range on the back are very small.

Standard SMA interface, aluminum alloy body

Using an acrylic panel + aluminum alloy body, it not only resists external signal interference, but also improves card reading accuracy. It has been widely used in unmanned retail, intelligent Library management and other fields.
