A Software Defined Radio Interrogator for Passive Harmonic Transponders

2021 IEEE 21st Annual Wireless and Microwave Technology Conference (WAMICON), 2021
Passive wireless sensors provide an opportunity for long term monitoring of remote environments. Such devices are activated with an interrogation signal which enables them to transmit information via a return signal. Some systems utilize the same frequency for interrogation and the return, which causes unwanted interference, particularly in cluttered ...
