| Abstract: | By embedding slots into a rectangular patch a triple-band slotted monopole antenna fed by a coplanar waveguide (CPW) with two asymmetrical ground planes can be obtained. The designed antenna, which, including the ground plane, is only 9/spl times/20 mm/sup 2/, can excite resonant modes at 2.43, 5.23 and 7.14 GHz bands with measured impedance bandwidths of 14.4, 8.2 and 16.7%, and average antenna gains of /spl ges/2.4, 4.7 and 6.7 dBi, respectively. The antenna is very compact and suitable for 2.4/5.2 GHz WLAN operations. |
