Abstract

A compact (31 mm,× 7 mm,×, 0.8 mm) uniplanar antenna designed for wireless local-area network (WLAN) operations in laptop applications is proposed. To achieve triple-band (2.4/5.2/5.8 GHz) WLAN operation, the structure of the proposed antenna is devised as an asymmetric dipole type, in which the 2.4/5.2 GHz operating bands are excited along the meandered feed line connected to a rectangular radiating element, and the excitation of the 5.8 GHz band comes from its asymmetric counterpart (with C-shaped parasitic strip). Interestingly, the proposed triple-band antenna can be reduced to a dual-band (2.4/5.2 GHz) one by simply tuning the length of the C-shaped parasitic strip. The simulated effects on the antenna performances by tuning the various vital parameters have been studied and experimentally verified.
