Contains symbols for VHF, UHF, and SHF circuit design, including capacitance measurers, nonreciprocal devices, modulators, phase shifters, field polarization devices, and filters.
In a UHF passive RFID system, a reader transmits an unmodulated continuous wave (CW) to tags, which not only provides energy to tags but also serves as the carrier of tag backscatter signals.
There's a UHF that has low data rates and that's for basic commands and telemetry communication and then an S Band which is for higher data rates like actually transmitting the pictures.
