Patent number: 9136594Abstract: A simple, compact multi-band PIFA including two arm portions, where one arm portion is grounded at two points to form a loop, a ground plane, and a plastic carrier and housing. The antenna radiates a same signal from both arm portions, at different efficiencies according to the radiated frequency and the effective length of each arm. The antenna is made from a single standard metal sheet by cutting it and is assembled with the metal ground plane and the other plastic parts. In one embodiment, the antenna is folded into a 3D U-shape to reduce its size for use in mobile communication devices. In another embodiment, the antenna is a penta-band antenna with return loss of ?6 B or better and measures 40×8×8 mm or smaller.Type: GrantFiled: November 16, 2009Date of Patent: September 15, 2015Assignee: QUALCOMM IncorporatedInventors: Guining Shi, Allen M.
