A compact multiband (GSM/DCS/PCS/UMTS/Bluetoo- th/WLANs/Wi-MAX) planar monopole antenna, which contains multiple branches, is proposed in this work. Most wireless communication bands for consumer electronics are covered in this design. The antenna radiator comprises four resonant branches on the top surface of a PCB board and one parasitic element on its back. The antenna size is 17:5mm £ 35:7mm, and no via is needed in the fabrication process. Various techniques, such as branching, meandered lines, closed loop, capacitive coupling, parasitic elements and tapered ends, are used to enhance the antenna's bandwidth, matching and size reduction performance. Simulation and measurement show good agreement for re∞ection coe-cient. The proposed antenna is particularly attractive for mobile devices that integrate multiple systems.
