Provided herein is a cancer detection and treatment instrument comprising: a first conductive plate; a second conductive plate which is opposed to the first conductive plate and has a first opening; a first signal line disposed between the first conductive plate and the second conductive plate; a first contact member of which one end is exposed through the first opening and of which the other end is connected to the first signal line; a dielectric portion filled between the first and second conductive plates and the first signal line; and a conductive layer surrounding both side surfaces and a front end surface of the dielectric portion which are exposed. Therefore, it is possible to accurately detect cancer by the use of the ultrahigh-frequency signal and to treat a diseased portion without damaging tissues around the diseased portion.

The present invention is concerning an element antenna to construct an efficient antenna system, which is able to control mechanical movement of micro-strip patch antenna and to control electrical phase of signal. The movement of an element antenna is come from movement of a platform on which the element antenna is formed. The platform is made of dielectric material and able to move independently from base. The element antenna can be controlled to any direction. An antenna patch has magnetic material layer such as nickel on the backside. The antenna patch is driven by magnetic force.

摘要:
A gateway enables mutual data communication between two or more networks by connecting the networks and forming a bypass path between the two networks to enable data communication therebetween when the gateway does not support a normal data communication mode. The gateway can form at least one physical communication path between the networks through the gateway even if the gateway cannot support a normal communication mode and/or power is interrupted to the gateway. Further, in spite of abnormal conditions, such as abnormal power supply to the gateway, if the bypass path is not formed, a user can compulsorily form the bypass path, thus improving reliability of a network system.

The present invention relates to a beam steering system. The system includes an array of a plurality of antenna elements, each antenna element being electrically and mechanically controlled for steering a beam in a specific direction, and a millimeter wave subsystem quasi-optically integrated with a 3-dimensional beam steering device and an MMIC-type active circuit. The antenna element is controlled in real time by an electrical driving method so as to be moved in 2-dimensional space. That is, in the 3-dimensional system of the present invention, the beam is electrically controlled by a phase shifter, and each antenna element is physically moved by a mechanical driving mechanism. The 3-dimensional beam steering antenna and the associated devices are monolithically integrated on a substrate using MEMS technology, and the active circuit elements such as a mixer, a power amplifier (PA), a low noise amplifier (LNA), a VCO, etc. are integrated in an MMIC active array. The 3-dimensional beam steering device and the active MMIC circuit are integrated into one system by being interconnected using the quasi-optical technique. According to the present invention, shortcomings of the millimeter wave in that the SNR is low due to the low device output and high transmission loss in the free space can be overcome using the new RF transmission technique of 3-dimensional beam steering, and by introducing a micro antenna structure which is electrically and mechanically controlled such that wideband RF communication and 3-dimensional imaging is allowed in a Pico cell environment.

A microwave tunable filter having some advantages as follows: a) the integration of MEMS tunable filter and MMIC; b) the very low signal transmission loss and low dispersion; and c) the drastic variation and linear characteristic of frequency by means of MEMS capacitor and an external control signal. The microwave tunable MEMS filter includes a plurality of unit resonant cells, each unit resonant cell being formed by various serial and parallel combination of an inductor, a capacitor, a transmission line, and a variable MEMS capacitor, whereby capacitance variation of the variable MEMS capacitor in the unit resonant cell converts a resonant frequency of the unit resonant cell to thereby convert a center frequency of the filter.
