Fig 1. Automatic antenna tuning with a variable impedance matching network can overcome many of the problems associated with detuning and wide frequency ranges. Feedback from the antenna via ...
Today's mobile phones need to not only support cellular frequencies, but also non-cellular features such as those used for mobile TV, Bluetooth, WLAN, and location-based services. As the real estate ...
This antenna tuning unit (ATU) enables half-wavelength or longer wire antennas to be matched to the 50-ohm antenna input of 27-MHz Citizens’ Band (CB) rigs. The ATU is useful in those cases where a ...
Simplified continuous tuning of filters, impedance matching networks, and antennas has become a crucial design element in modern mobile devices. Wireless 3G/4G technologies, Wi-Fi, Bluetooth, GPS, and ...
