A planar inverted-F type reconfigurable antenna with slot is presented. The antenna can cover frequency bands which include Digital Cellular Service (DCS: 1710–1880 MHz), Personal Communication Service (PCS: 1850–1990 MHz), and Universal Mobile Telecommunications System (UMTS: 1900–2200 MHz). Initially, the reconfigurability of the proposed antenna is achieved by attaching lumped capacitor over the slit of the radiator with values range from 1.5–4pf. The measured and simulated results reveal that the fabricated proposed antenna is capable of obtaining tunable frequency ratio from 1850MHz to 2200MHz with overall size of 21×13.5×5 mm3 that makes it suitable for handset applications and can be easily integrated inside commercial mobile handsets.
