An antenna apparatus includes: a substrate; an RF ground conductor which is branched to extend in at least two directions and at least a part of which is formed on a surface of the substrate, the RF ground conductor functioning as an antenna ground plane; and an antenna portion, one end of which is connected to the RF ground conductor.

Antenna apparatus

An inductive lightening surge installed at input and output circuits or other locations of circuits of communication devices where a surge noise may be generated or a surge absorber for avoiding failure and erroneous operation of electronic devices by mixed contact or the like of AC circuits in which a first terminal electrode,, a conductive film,having a micro-gap,and a second terminal electrode,are formed in shapes of concentric circles on an insulating substrate,in a flat plate shape.
