Radio-frequency identification (RFID) technology is a relatively new and popular method for identifying, tracking, and retrieving data from objects without direct contact or line-of-sight contact. It is used for a variety of applications, including inventory control, animal identification, asset tracking, access control, and product authentication. RFID antennas are a key component to the efficient function of RFID systems. Different antennas are used depending on the specific application, but all RFID antennas have several common attributes.

In RFID systems, the antenna is one of three components, along with a reader and tag. The antenna transmits energy to the tag, the tag receives a unique identifier from the reader, and the tag transmits its response back to the reader. The reader then interprets the response and sends the data to the necessary software system for processing.

The RR-IDISC-ANT-PS-B is an RFID antenna designed specifically for passive (non-battery powered) RFID applications. It features a foldable double-circle array manufacturing technique that results in a compact size. This antenna is able to maintain a consistent read rate throughout its directivity angle, providing an efficient and reliable RFID solution.

As with all antennas, the RR-IDISC-ANT-PS-B has specific performance metrics that are required to achieve an accurate and efficient read rate. Its return loss (RL) is typically around –20 dB, and its antenna gain is between 2.5 and 3.0 dBi. The radiation pattern of this antenna is circular, meaning that the signals spread evenly in all directions. This type of antenna is also relatively fixed frequency, meaning that it is tuned to a specific frequency and can only be used to read tags within that frequency range.

In operation, the RR-IDISC-ANT-PS-B transmits RF energy from the reader to the tags, and it also receives the returned energy from the tags. This received energy is then amplified and decoded by the reader, which is responsible for communicating the data to the connected software system. The reader must be connected to a power source, as the antenna is a passive device and does not require any external power.

The RR-IDISC-ANT-PS-B is an ideal choice for any RFID application with non-battery powered tags. Its compact size and wide coverage make it a great choice for a variety of applications, such as tracking inventory, managing assets, or providing access control. With its efficient operation and accurate read rates, the RR-IDISC-ANT-PS-B is an essential RFID antenna.
