A planar inverted L-slot antenna is proposed covering different bandwidth applications. The open slot antenna configuration for GSM/DCS/PCS/UMTS/WLAN bands is described. The inverted-L slot antenna system composed of filter circuit within microstrip feed line to enhance the bandwidth. For LC band pass filter, the value of inductor and capacitor is calculated parametrically. The antenna achieves frequency range 1710-2690 MHz for -10dBreturn loss. The S11 parameter for antenna with filter and without filter is discussed.
