Abstract
Disclosed is an apparatus for a wireless communication device 102 with a multi-band antenna system 106 supporting three common modes and one differential resonant mode. The multi-band antenna system 106 comprises a printed circuit board (PCB) 202 with a feeding contact 206, a conductor 208 that extends completely out of a PCB ground 204, wherein the conductor 208 has no ground contact with the PCB ground 204. The conductor has an enclosed slot 210. The conductor is fed with signals using a feed line 228 which is coupling the conductor 208 to the feeding contact 206.
Claims15
