A novel multi‐ and ultrawideband operation of a single feed triangular antenna are presented. For multi and UWB operation, the proposed design are achieved by inserting U shaped slot on the triangular PIFA with unequal arms, choosing between multi and ultrawide band by adjusting feeding position. Five resonant band of multi band operation is obtained in S‐band, Q‐band, bluetooth band, and WLAN band with acceptable impedance bandwidth. There is an increase in the number of resonant operating frequencies by etching U slot on the shorting feed plate. Ultrawideband is achieved by adjusting coaxial feed to obtained impedance bandwidth 27%. Enhancement impedance bandwidth by using folded shorting plate to improving bandwidth to achieve ultrawide bandwidth around 53%. The proposed antennas have acceptable gain around 11.5 dB. © 2007 Wiley Periodicals, Inc.
