摘要
A novel, one-piece, loop-like plate antenna that shows a symmetrical structure is proposed for wireless LCD TV applications in the 2.4/5.2/5.8 GHz bands. The antenna was constructed by stamping a rectangular, flat plate of size 30 mm x 70 mm and bent two times to form a 3D configuration of volume 10 mm x 10 mm x 70 mm. The design consists of a main radiating portion, one grounding portion, and one shielding wall. The radiating portion includes a symmetrical loop-like structure and is able to generate multiple resonance. The antenna is easily affixed to the top wall of the display ground by making use of the grounding portion, and at the same time shielded from the hack metal casing of the wireless thin LCD TV by the shielding wall. These arrangements make the antenna very easy to feed on both short sides and facilitate the feeding-cable routing to the Wi-Fi module on the back of the TV. Four possible cases of the antenna installed in a 42-inch, widescreen LCD TV were investigated on the radiation performance. Details of the design prototypes are discussed in this article.
