In this paper, a novel coplanar waveguide (CPW)-fed and miniaturized slot antenna for triple-frequency operation is proposed and investigated, which is printed on a small 20mm×20mm FR4 substrate with thickness of 1.0 mm and relative permittivity of 4.3. Through loading different slits, three perfect operating bands of 2.4GHz-2.45GHz, 3.25GHz-4.15GHz and 5.05GHz-6.25GHz are achieved respectively, when return loss is less than-10dB. Experimental results show that the antenna gives monopole-like radiation patterns and good antenna gains over the operating bands. Such antennas is suitable for WLAN 2.4/5.2/5.8 GHz and WiMAX 3.5/5.5 GHz applications.
