Abstract: A frequency reconfigurable phased array system comprises a signal generator outputting a power signal with an adjustable frequency, a plurality of radio frequency (RF) modules receiving the power signal, a control module generating excitation mode parameter sets and material processing event sets, a first database storing the excitation mode parameter sets, and a second database storing the material processing event sets. The control module generates a material processing schedule by selecting one of the material processing event sets based on a material recipe, an average power, and a total time of a material, and controls a signal frequency of the signal generator according to the material processing schedule and the excitation mode parameter sets, and a RF phase and a RF power of each of the RF modules, to have the RF modules generating a power signal.

Abstract: A multi-antenna system including a substrate, a ground element, a first antenna element, a second antenna element and a decoupling element is provided. The ground element is disposed on a first surface of the substrate, and the decoupling element is disposed on a second surface of the substrate. Ground portions of the two antenna elements and a first connection terminal of the decoupling element are electrically connected to the ground element. The decoupling element is spaced a first decoupling distance from a part of the first ground portion, and the decoupling element is spaced a second decoupling distance from a part of the second ground portion. A phase difference relative to the two antenna elements is generated by the decoupling element, the first decoupling distance and the second decoupling distance so as to eliminate interference energy between the two antenna elements.
