    Abstract: 본발명은, 일반적으로하나이상의안테나를갖는, 이동전화또는웨어러블장치와같은무선통신가능한임의의장치에관한것이다. 가변리액턴스(용량성또는유도성성분) 안테나어퍼처튜너(variable reactance antenna aperture tuner)를단순한스칼라안테나어퍼처튜닝시스템에적용함으로써, 환경적효과또는헤드/핸드효과의존재시 일정한안테나공진주파수를유지할수 있다. 가변리액턴스는, 안테나의공진주파수를장치의작동주파수에서멀어지게변경시킬수 있는외부변수들에대응하여안테나의공진주파수를원하는목표주파수에서유지되도록조절하는데사용된다. 외부적으로유도된변화에대응하여안테나의공진주파수를조절함으로써, 안테나의방사효율을유지하고, 동시에안테나와무선부내의각각의송신/수신경로간의임피던스부정합이방지하여, 전송손실을최소화할수 있다.

    Abstract: The present invention generally relates to an architecture for isolating an RF MEMS device from a substrate and driving circuit, series and shunt DVC die architectures, and smaller MEMS arrays for high frequency communications. The semiconductor device has one or more cells with a plurality of MEMS devices therein. The MEMS device operates by applying an electrical bias to either a pull-up electrode or a pull-down electrode to move a switching element of the MEMS device between a first position spaced a first distance from an RF electrode and a second position spaced a second distance different than the first distance from the RF electrode. The pull-up and/or pull-off electrode may be coupled to a resistor to isolate the MEMS device from the substrate.

    Abstract: Embodiments disclosed herein generally include using a large number of small MEMS devices to replace the function of an individual larger MEMS device or digital variable capacitor. The large number of smaller MEMS devices perform the same function as the larger device, but because of the smaller size, they can be encapsulated in a cavity using complementary metal oxide semiconductor (CMOS) compatible processes. Signal averaging over a large number of the smaller devices allows the accuracy of the array of smaller devices to be equivalent to the larger device. The process is exemplified by considering the use of a MEMS based accelerometer switch array with an integrated analog to digital conversion of the inertial response. The process is also exemplified by considering the use of a MEMS based device structure where the MEMS devices operate in parallel as a digital variable capacitor.
