A resonance element supported by a bearing structure includes a crystal chip and an excitation electrode. The crystal chip includes a main surface having a support surface portion being in contact with the bearing structure. The excitation electrode is disposed on the main surface, has an electrode area, and includes an electrode indentation boundary partly encompassing the support surface portion. The electrode indentation boundary has a first boundary end and a second boundary end being opposite to the first boundary end. The electrode indentation boundary and a reference line segment defined by the first and the second boundary ends form an electrode indentation region having an indentation area. A ratio of the indentation area to the electrode area ranges from 0.05 to 0.2.

Crystal device and resonance element

A crystal device includes a bearing base, an integrated chip and a conductive adhesive unit. The bearing base includes a conductive seat. The integrated chip includes a principal reference plane facing the conductive seat, and having a first major axis. The conductive adhesive unit has a second major axis and an aspect ratio, and is at least partly disposed between the conductive seat and the integrated chip. The aspect ratio ranges from 1.1 to 1.9. The principal reference plane further has a perpendicular projection straight line defined according to the second major axis. A practical angle is included by the first perpendicular projection straight line and the first major axis, and ranges from 0 degree to 90 degrees.

Crystal device and method for manufacturing crystal device

The present invention provides to an antenna. The antenna includes a piezoelectric-substrate layer; and a quasi-fractal radiating layer disposed on the piezoelectric-substrate layer and having a quadrangle sub-structure and a similar structure that is formed by a nth-order self-similar iteration process including a trimming step, a scaling step and a combining step on the basis of the quadrangle sub-structure, where n is an integer greater than zero.

Quasi-fractal antenna

Sacrificial electrodes with fractal-shaped are formed on a SAW (surface acoustic wave) device. The sacrificial electrodes discharge electro-static charge in the SAW device for protecting the IDT (inter-digital transducer) from electrostatic break. Moreover, the sacrificial electrodes can control the path and the discharging degree of the electro-static discharge to avoid losing the electro-static discharge protection due to the sacrificial electrodes are broken.
