Abstract: An antenna system is disclosed. The antenna system includes a printed circuit board, a metallic frame surrounding and electrically connecting with the printed circuit board, a low frequency antenna unit electrically connecting to the metallic frame and an antenna feed, a high frequency antenna unit electrically connecting to the metallic frame and the antenna feed, a ground terminal disposed on the metallic frame for grounding the metallic frame, and an adjusting terminal for being grounded via a matching component for adjusting the low frequency performance of the antenna system. The antenna system enables covering the operational frequency bands of 791 MHz˜960 MHz, and 1710 MHz˜2690 MHz. By virtue of the adjusting terminal, ultra wide low frequency of dual-resonance is accordingly performed.

Abstract: The present disclosure provides a piezoelectricity ceramic material. The piezoelectricity ceramic material includes main components that are represented by a general chemical formula of PbZraTib(Nb2/3Ni1/3)1-a-bO3+c%BaW0.5Cu0.5O3 d%SiO2 and satisfy the following condition: 0.1?a?0.4, 0.2?b?0.5, 0.1?c?3, and 0.05?d?1. The low-temperature sintering adopted by the present disclosure reduces energy consumption and reduces the volatilization of PbO, which avoids the fluctuation and deviation of the ceramic components, reduces the pollution to then environment caused by volatilization, and reduces the corrosion to the sintering machine as well. Furthermore, the present disclosure provides a piezoelectricity ceramic sinter and a method for processing the same, as well as a piezoelectricity ceramic device. In a multi-layer device, the device cost is greatly reduced.

Abstract: Disclosed is an array camera. The array camera includes an array camera comprising an image sensor sectioned into at least two channels and at least two lens modules each positioned on a top of one of the channels. Each channel consists of an active sensor area and a dead space. Each lens module has a barrel. Each barrel of the lens modules has an inner sidewall facing the adjacent lens modules and an outer sidewall opposite to the inner surface. Wherein, a projection of the inner sidewall of each barrel along the optical axis is an inner line on the corresponding channel of the image sensor and the inner line is substantially superposed with a part of the outline of the active sensor. The array camera has a small size.

Abstract: Disclosed is an integrated lens stack manufactured by dicing a wafer. The integrated lens stack includes an image sensor, at least one lens modules located on the image sensor. Each of the lens modules has a top lens, a bottom lens, and a middle lens between the top lens and the bottom lens, the bottom lens including a first active area and a second active area opposite to the second active area for collecting light, respectively. A chamber is formed between the middle lens and the bottom lens and is a closed room. An area of the first active area is sufficiently smaller than an area of the second active area.
