Abstract
A planar inverted F antenna includes a radiation portion to receive or transmit a radio signal, a short portion having one end connecting to the radiation portion to brace the radiation portion, a ground portion connecting to the short portion on another end, and a feed section located between the radiation portion and the ground portion, wherein the feed section has one end connecting to the radiation portion and another end directed towards the ground portion but not connected to the ground portion. The radiation portion, short portion, ground portion and feed section are formed in an integrated manner.
Claims26
A planar inverted F antenna, comprising:
- a radiation portion receiving/transmitting signals, wherein the radiation portion has a first opening and a match portion located in the first opening, the match portion having two ends connected to the radiation portion, and the first opening being larger than the match portion;
- a short portion having one end connected to the radiation portion to brace the radiation portion;
- a ground portion connecting to the short portion on another end thereof;
- and
- a feed section located between the radiation portion and the ground portion and the feed section, the feed section having one end connected to the radiation portion and another end directed towards the ground portion without connecting to the ground portion.
