UHF RFID Antennas

Twelve JNXTECH UHF antennas, from ceramic elements for compact read points to 12 dBi panels for yard and portal coverage. Pick the antenna by the read zone you actually need to cover, not by the biggest gain figure on the page.

Pick by read zone

Every antenna on this page is supplied under the JNXTECH JNA series. They are built to pair with fixed RFID readers, so antenna and reader are best chosen together: if you already know the reader, start from the zone you need to cover; if you do not, we will size the pair with you.

How to choose

Five things decide whether an antenna works in the field. They matter more than the model number.

Read zone size

Low-gain elements cover a small, defined read point. An 8 to 12 dBi panel reaches across a portal, a dock door or down an aisle. Choose the smallest antenna that covers the zone you actually have — extra gain does not help if it spills into the next lane.

Element type

Ceramic-core antennas are the smallest option and suit desktop stations, kiosks and embedded reader designs. PCB and panel types carry the mid and long ranges.

Beam shape

A standard circular panel reads in a broad cone. Narrow-beam models concentrate the beam along an aisle or conveyor, which is how you stop a neighbouring zone from reading your tags.

Near field

Where a tag must only be read while it is directly in front of the antenna, a near-field antenna replaces gain with a tightly bounded coupling zone — the usual answer for anti-misread lanes and exception stations.

Band and region

Some models cover the US 902-928 MHz band only; others cover both US and EU 865-868 MHz. Confirm the band against the region the reader is deployed in before ordering.

How do I get help choosing the right model?

Send us the tag type, read zone and environment. JNXRFID shortlists the models that fit, explains the trade-offs, and supplies a single evaluation unit before volume orders. Contact us for current lead time and evaluation terms.

Not sure which antenna fits your zone?

Send us the reader you are using, the distance and the environment. We will shortlist two or three options and explain the trade-offs.
