A miniaturized dual-band dipole antenna with a modified meander line for laptop computer application in the 2.5 and 5.25 GHz WLAN band

In this paper, a reduced size dual-band balanced antenna is presented and tested in a lid of a laptop computer. The antenna size is only 0.28 /spl lambda//sub 0/, which is 44% smaller than the conventional dipole antenna and is comparable to the size of unbalanced antenna. A modified meander line technology is used in the particular antenna configuration to achieve dual-band operation in the 2.5 and 5.25 GHz WLAN bands.
