Adaptive self-tunable antenna system and method

摘要: Adaptive self-tunable antenna systems and methods are provided including a closed-loop system for sensing near-field RF signals of transmitted tuning an or switching between multiple antennas, so that the strength is maximized. A detects signal, which filtered converted to control signal can be used generate signal. An tuner uses keep in resonance by dynamically changing electrical length antennas maximize radiated Such may less prone detuning due interaction with human bodies other objects. Dynamically matching power amplifier low noise improve stability, efficiency, gain, figure, receiver sensitivity.
