摘要： A relaxor ferroelectric composition that has the components lead magnesium niobate, lead titanate, and lead magnesium tungstate. The components are preferably present in relative molar amounts of (1-x-y) lead magnesium niobate, (x) lead titanate, and (y) lead magnesium tungstate, where 0.11.ltoreq.x.ltoreq.0.13 and 0.01.ltoreq.y.ltoreq.0.03. Also disclosed is a tunable ultrasonic transducer made of a relaxor ferroelectric composition that has the components lead magnesium niobate, lead titanate, and lead magnesium tunstate. A method of making a relaxor ferroelectric material comprising the step of adding an effective amount of lead magnesium tungstate to a lead magnesium niobate-lead titanate composition is also disclosed.

摘要： A method for manufacturing microchip antenna comprises a dielectric substrate having antenna radiation conductor paths composing of at least one feeding point and multiple-curved paths; a dielectric substrate having the antenna radiation conductor paths being packaged by the material capable of adjusting easily dielectric constant; and an antennal object including antenna radiation conductor paths, feeding ends, welding spots and packaging materials. The main body of the antenna has multi-folded paths, feeding ends, welding spots, and a packaging body. The radiation wires of the antenna is built on a single or a multiple input ends on a dielectric substrate and is multi-folded wires and it is packaged by another dielectric material. The radiation wires of the antenna can be designed and manufactured in three dimension so as to reduce the area occupied by the antenna and reduce the coupling interference between the elements.
