Abstract: Disclosed are composition and structure of an over-voltage suppressor. One or more non-conductive materials in powder form or non-conductive materials with conductive and/or semiconductor particles are mixed well and then heat-treated to form a nonconductive porous material that is full of non-closed air pores. A film of this porous insulator of controllable thickness is sandwiched between a pair of upper and lower conductor electrodes to form the over-voltage suppressor. This over-voltage suppressor offers the advantages of fast response, low leakage current, low capacitance, easy manufacturing, and high reliability.

Abstract: Disclosed is a method for insulating external surfaces of a multi-layer ceramic chip varistor device, wherein a high insulating material is coated on external surfaces of the device before the device's external electrodes are plated in an electroplating process. Then after a heat treatment process, the high insulating material reacts with the device's ceramic body surface material to form an insulating layer. A conventional electroplating process for chip devices can be applied to plate the device's external electrodes with a layer of soldering interface so that the external electrodes have a better solderability. The insulating layer protects the device's ceramic body from being plated and the external electrodes are not short-circuited to cause device failure.

The microstrip antenna layer and the metal layer adhere respectively to opposite sides of the single-layer substrate, wherein the metal layer works as the electrical ground. The single-layer substrate contains a penetrating opening whose diameter and location are predetermined. The task of transmitting and receiving dual-band or multi-band signals is carried out by feeding the microstrip layer with signals from a connector, such as a coaxial connector, through the penetrating opening.

Abstract: A broad-band microstrip antenna implemented using a dielectric base as its main body is disclosed. The base has two sides where the dual-mode resonator is located on the first side, while the grounded plane is located on the second side of the dielectric base. The dual-mode resonator has a high-frequency resonator and a low-frequency resonator, which are partially positioned in parallel. Due to the electric-magnetic effects, these two resonators are mutually coupled to significantly increase the operating bandwidth. In addition, there is a feed line on the first side of the dielectric base, which connects to the dual-mode resonator to provide signal transmission. In addition, there is a grounded mask in the antenna, which is located on the first side of the dielectric base, to provide sheltering for the feed line, and connect to the grounded plane to form a closed area to provide a more complete radiation field pattern.
