A novel printed dual band antenna structure operating at UMTS and HIPERLAN2 bands: Narrow CPW-fed sleeve monopole
Soodmand S., Ghobadi C., Nourinia J.
By using of a new coplanar waveguide feeding (CPW feeding) technique to a planar sleeve monopole, a narrow width antenna with uniplanar structure is proposed for dual band operation at UMTS (1.885-2.200GHz) and HIPERLAN2 (5.470-5.725 GHz) bands. Proposed antenna has considerable narrow width (width of 7.8mm) and simple structure. The antenna radiation pattern is almost as the radiation pattern of a monopole antenna and the gain remains nearly constant within UMTS and HIPERLAN2 bands. The antenna is suitable for application to wireless communication systems.
