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 ...

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 ...

Antennas truly are the tiny, unsung heroes of wireless networking. Whether you’re at home, in the car, or walking around with a phone in your pocket, it’s antennas that keep you connected. The Shannon ...

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 ...
