摘要： Embodiments of this application disclose a variable capacitor-based antenna adjustment method and a related apparatus. A first signal strength of a first communications system with a highest priority that is supported by an antenna having a variable capacitor is detected, and when the first signal strength is relatively strong to meet a first release condition, a capacitance value of the variable capacitor is adjusted to a preset capacitance value, where the preset capacitance value is closer to a second capacitance value corresponding to a working frequency band of a second communications system supported by the antenna, so that a working frequency band of the antenna having the variable capacitor is closer to the working frequency band of the second communications system, and therefore, communication quality of the second communications system is improved. Although the first signal strength is attenuated, because the first signal strength is very strong before the attenuation, the attenuated first signal strength can still meet a communication quality requirement on the first communications system. Therefore, this application can give consideration to communication quality of multiple systems supported by the antenna having the variable capacitor.

摘要翻译：本申请的实施例公开了一种基于可变电容器的天线调整方法和相关装置。检测具有可变电容器的天线所支持的具有最高优先级的第一通信系统的第一信号强度，并且当第一信号强度相对较强以满足第一释放条件时，可变电容器的电容值为调整到预设的电容值，其中预设的电容值更接近与天线支持的第二通信系统的工作频段对应的第二电容值，使得具有可变电容器的天线的工作频段更靠近到第二通信系统的工作频带，因此提高了第二通信系统的通信质量。尽管第一信号强度被衰减，但由于第一信号强度在衰减之前非常强，所以衰减后的第一信号强度仍然能够满足第一通信系统上的通信质量要求。因此，该应用可以考虑具有可变电容器的天线所支持的多个系统的通信质量。

摘要： Surface scattering antennas provide adjustable radiation fields by adjustably coupling scattering elements along a wave-propagating structure. In some approaches, the scattering elements are patch elements. In some approaches, the scattering elements are made adjustable by disposing an electrically adjustable material, such as a liquid crystal, in proximity to the scattering elements. Methods and systems provide control and adjustment of surface scattering antennas for various applications.

摘要： A node in a wireless communication system comprising an antenna array with at least a first antenna function and a second antenna function. The node further comprises a first radio chain and a second radio chain, where each antenna function is connected to a base band via a corresponding radio chain. Each radio chain comprises an oscillator, a splitter and a multiplexer, each oscillator being arranged to feed a signal with a unique frequency band to the splitter in the same radio chain. The splitter is arranged to divide the signal into at least two signal parts and feed each part to the multiplexer of each radio chain such that each multiplexer in the node receives signal parts from each splitter in the node. The splitter is arranged to weight the division of the signal into the signal parts in dependence of the frequency bands fed by each oscillator.

摘要： A millimeter wave concealed weapons and contraband detection system. The preferred millimeter wave imaging equipment includes at least one millimeter wave frequency scanning antenna for collecting frequency dependent beams of millimeter wave radiation from a narrow one-dimensional field of view. The collected radiation is amplified at the collected frequencies and the amplified signals are separated into frequency dependent bins with a tapped-delay beam-former. These bins are then sampled to produce a one-dimensional image of the antenna field of view. A two dimensional image of a target may be obtained by moving the target across the field of view of the scanning antenna or by moving the antenna in order to scan its line of focus over the target. In preferred embodiments the millimeter wave imager is combined with an active eddy current type metal detector to provide a hybrid system providing important advantages over prior art security systems. Preferred embodiments include hybrid portal systems and hybrid handheld systems.
