how to determine the range of a passive rfid tag Passive RFID tags harness energy from an RFID reader’s emitted Radio-frequency (RF) signal. When the reader sends a signal, it creates an electromagnetic field that energizes the tag. The tag captures this energy and powers its internal chip, enabling it to transmit data back to the reader.

#1. What Is Read Range? Read range is the distance from which an RFID tag can be detected. The read range expresses the distance from which the tag receives just enough power to be activated to send back a signal to the reader. #2. How Is Read Range Determined? Generally, the manufacturer spec sheet includes RFID read range information. In this article, we will explore the factors that can influence the maximum effective range of a typical passive RFID tag. We will also discuss how to maximize the range of a passive RFID tag and examine the applications and limitations of this technology.
We’ll look at how we can make use of COMSOL Multiphysics® simulation software to determine the operating read range of a passive RFID tag powered by a reader’s interrogating field. Additionally, we will look at how we can maximize this operating range by optimizing the tag’s antenna design.Read ranges will vary significantly so we will go into the details of what factors affect the range of RFID tags. Primary factors of RFID read ranges are: 1. Type of reader and the antenna on the reader (could be handheld or fixed readers) 2. Type of asset being tagged. 3. Type and size of the RFID tag being used. 4. With these considerations in mind, the typical read range for passive RFID tags is generally between a few centimeters to several meters. Low-frequency (LF) passive RFID tags, operating at frequencies around 125-134 kHz, typically have a shorter read range compared to higher-frequency tags. There are mainly two ways this can be achieved: The first one relies on getting the RSSI, which is basically the signal strength. The main difficulty using this indicator is that signal strength depends on a lot of factors that can influence it like, reflections if the signal needs to pass a wood cabinet or a wall, the quality of the tag, etc.
Passive RFID tags can vary in read range from a few inches to 50+ feet. RFID tags contain small, metal antennas; because larger antennas will broadcast farther than smaller antennas, generally the larger the tag, the longer the read range. Check out the video below to see tag size in action. Passive RFID tags are ideal for short to medium-range applications, typically up to a few feet. Within the category of passive RFID tags, there are further distinctions based on their operating frequency, including low-frequency (LF), high .How to Optimize RFID Tag Range.
