Abstract
A PIFA for a thin communication apparatus is provided. The PIFA includes a main body, a ground area and two ground segments, wherein the ground segments are adjacent with each other and extending out from a same side of the ground area. The SAR value and a required height for setting the antenna can be reduced through the design of two grounding paths on the antenna.
Claims16
A planar inverted F antenna (PIFA), comprising:
- a main body, including a first radiation area and a second radiation area, wherein the first radiation area is directly extending out from a ground area and is directly connected to the second radiation area and is bent in a first direction perpendicular to the ground area to form a first plane and a second plane, the first plane and the second plane form a three dimensional structure, the second radiation area which is not directly connected with the ground area is directly extending out from the second plane and bent in a second direction parallel to the ground area to form a third plane and a fourth plane, and the third plane and the fourth plane form the three dimensional structure;
- a first ground segment, directly extending out from the ground area directly-electrically connected to the main body for connecting to ground;
- and
- a second ground segment, directly extending out from the ground area directly-electrically connected to the main body for connecting to the ground,
- wherein the first ground segment and the second ground segment are parallel with each other, a spacing distance between the first ground segment and the second ground segment is between 1 mm and 10 mm, and a width of at least one of the first ground segment and the second ground segment is less than 2 mm.
