RFID antennas use various frequency ranges, including the LF (Low Frequency) 125 kHz and HF (High Frequency) 13.56 MHz bands, in addition to UHF below 800 MHz (e.g. 433 MHz). Here is the key information about them:

1. LF band (125 kHz) :

Range : Short ranges, usually up to a few centimeters.

Usage :

- Access control : Identification of employees and building security.

- Payment systems : Payment and ticket cards.

- Animal identification : Microchips for pets and farm animals.

Advantages :

- Metal Resistance : Works well in the presence of metal and water.

- Low power consumption : Effective in applications requiring low power consumption.

2. HF band (13.56MHz) :

Range : Medium ranges, typically up to 1 meter.

Usage :

- Proximity cards : Identification in access control and payment systems.

- Libraries : Track books and resources.

- Public transport : Electronic tickets.

Advantages :

- Fast data transmission : Higher throughput than LF.

- Interoperability : ISO 14443 and ISO 15693 standard, widely used around the world.

3. UHF band (433MHz) :

Range : Longer ranges, usually up to several dozen meters.

Usage :

- Logistics : Goods tracking and warehouse management.

- Asset Monitoring : Track tools and equipment.

- Industrial automation : Identification of components in production processes.

Advantages :

- Long range : Reading from greater distances.

- Data throughput : Ability to read multiple tags simultaneously.

- Interference Immunity : Better immunity to RF interference and material barrier than HF systems.

To sum up, RFID antennas operating in the LF (125 kHz), HF (13.56 MHz), and UHF (433 MHz) bands have various applications and advantages, which allows them to be widely used in various industries and applications.
