Times-7 are excited to be launching our new Near Field antenna range, the A1115, A1130 and the A1163.
True Near-field antennas have only a weak electronic field and operate using the magnetic field on the antenna’s surface only. Their unique abilities open a wide range of opportunities to improve the read accuracy in a variety of applications, where far field antennas would fail.
General Near field antenna benefits:
- Close proximity tag reading
- Avoid unwanted stray reads
- Ideal for liquids and metals tracking
What makes Times-7 Near field antennas so special:
- No surface dead zone
- Times-7 True near field antennas operate using magnetic energy radiator only (less far-field components than common NF antennas in the market)
- The Times-7’s near-field antenna design is the first and only antenna that can scale in size.
- Very large footprint available, which lowers the cost and complexity during installation as less readers, cables etc are required
Applications for UHF RFID Near Field Antennas
Near Field antennas can be used for a wide range of applications, which require to read tags in a very close range and focused read zones.
The close proximity read range of a near field antennas used in shelving applications allows for tracking items on each individual shelf avoiding stray reads in neighbouring shelves or items which are passing by. This allows for a more defined and focussed read area, in which you gain visibility over the items that you want to track.
Near field antennas are ideal for applications involving liquid in either the item or the storage environment of the items. Liquids absorb RF radiation and decrease the read zone.
A Near field antenna will achieve stronger read results because of the close proximity to the tracked item which means that minimal RF radiation will be absorbed by the liquid.
Metal environments affect the performance of far field antennas in such a way that it lowers the gain or reflects the RF energy, resulting in an inconsistent read range and read losses.
Near field antennas are ideal for applications, which involve metal. Since it operates using the magnetic field on the antennas surface only it will not be affected by the side effects of metal that will normally impact Far field antennas.
Using a Near Field antenna for POS systems is a great way to reduce the time identifying each item at the check out counter. A NF antenna can instantly and correctly identify all items that are placed on the antenna so long as the items are tagged appropriately. Having the items in close proximity to the NF antenna means that any items moving past or around the antenna cannot be unintentionally read which could result in the customer paying for items they did not want to purchase.
It is important when using a NF antenna that you tag the items you want tracked with NF tags to ensure tracking accuracy.
