CPW-fed wideband planar monopole antenna for operations in DCS, PCS, 3G, and Bluetooth bands

A novel CPW-fed wideband planar monopole antenna with a symmetrically slope ground plane is proposed. By choosing the suitable slope angle of this symmetrically slope ground plane, wideband operation can be obtained. From the experimental results, the operating mode has an impedance bandwidth of about 1162 MHz (1700-2862 MHz) that covers the DCS band (1710-1880 MHz), PCS band (1850-1990 MHz), 3G band (1920-2170 MHz), and Bluetooth band (2400-2483 MHz). The proposed antenna within these operating bands has similar monopole-like radiation patterns. It is suitable for application to wireless communication systems with its relatively low profile.
