I'd like to design an RFID reader with 4 output antenna ports. My RFID reader's module maximum output power is 30 dBm.
My target is for the maximum output power in the antenna ports to be 30 dBm.
If I use an RF switch to configure the antennas, I will have power losses and the power of ports will be less than 30 dBm.
Can you recommend a way to switch between antennas that won't cause losses?
