The measured S11 has a resonance at K-band with a -10dB valid bandwidth of 3GHz (17GHz ~ 20GHz). The Ka-band array obtains a -10dB impedance bandwidth of 12% (27.4GHz ~ 30.9GHz).

It has considered for each band the uplink and downlink frequencies, including the frequency bands 3400-3700 and 6425-6725 MHz (‘extended C-band’), 4500-4800 and 6725-7025 MHz (‘planned C ...

The K-Band U.S. Tour radiometer addresses the critical issue of identifying radio frequency interference (RFI) disruptive to weather forecasting and other scientific endeavors. Our product is a ...

However, this option, thus far, has been ignored by certain wireless providers seeking absolute control over the desired 3.1–3.45 GHz band to compete in the current 5G and future 6G markets.

Expanding into the 6 GHz spectrum band will ensure the community can continue to make the enhancements necessary to pave the way for the next twenty years of Bluetooth innovation.” ...

Most of the previous 6 GHz frequency bands were only for certain devices with a license. Apple, Microsoft, Meta, and other brands applied to the FCC in 2019. They were requesting the unauthorized ...
