Abstract

A very small-size (10 × 6 × 0.4 mm ) uniplanar meandered monopole antenna that is fed by a 50-Ω mini-coaxial cable for laptop computer applications is proposed. To achieve dual-band 2.4/5-GHz wireless local area network (WLAN) operation, a protruded tuning stub is introduced into the meandered monopole structure. The achieved 10-dB bandwidths of the lower and upper operating bands in free-space condition are 12% (2360-2660 MHz) and 20% (4870-5960 MHz), respectively. Further experimental studies are also conducted by mounting the proposed antenna onto an actual laptop computer that works as the host platform.
