An electronic device which includes a radome, a bottom cover connected to the radome, and a printed circuit board disposed between the radome and the bottom cover. The radome includes a top shell, an insulating member and at least one fastening members. The insulating member is made of expanded polystyrene and has at least one recess. The fastening member is embedded in the insulating member. The top shell covers the insulating member and includes polycarbonate.

Electronic device

The present disclosure provides an electronic system including an electronic device and an electronic tag. The electronic device includes a printed circuit board. The electronic tag includes a substrate and an antenna, wherein the substrate is disposed at a height over the printed circuit board. The substrate has a first side and a second side, wherein the first side is opposite to the second side. The antenna has a first portion and a second portion, wherein the first portion is disposed on the first side, the second portion is to disposed on the second side, and the first portion is electrically coupled to the second portion via plated through holes.

Electronic tag and electronic system using the same

The present disclosure provides an antenna apparatus and a circuit board thereof for an RFD device to provide wide field effect coverage. The antenna apparatus includes a housing having a concavity defined therein, a printed circuit board disposed inside the concavity of the housing, two plates respectively located on opposite side portions of the circuit board, and a metal pattern sandwiched between and wirelessly coupled to the two plates. By disposing the metal pattern at the central portion of the circuit board and sandwiched between and coupled to the two plates, the field effect is enhanced, and the sensitivity of the antenna apparatus when detecting an object passing through the field (near field detection) is improved.
