Is There a Relationship Between the Read Range and Gain of an RFID Antenna?
If so, what does a higher gain mean for the antenna's range?
Yes, there is. An antenna's gain is a measure of the amount of power transmitted in a specific direction. A higher gain essentially means more energy is emitted and thus reaches the tags, allowing them to transmit a further distance.
