Antennas

The RE40 RFID module supports one monostatic bidirectional RF antenna port through castellated pad,

which may be connected to a 50 ohm controlled impedance connector for the antenna. The module also

Using a Multi-port RF Switch

The module supports using an RF switch, allowing up to four total logical antenna ports. RF switching is

While a short period of exposure to 5dB or less is not expected to significantly harm the module, the

module should never transmit in an open port. Damage may occur if an antenna is disconnected during

operation or if the module observes a short circuit at the antenna port.
