A printed microstripline‐fed parallelogram monopole antenna for wideband applications is presented.This antenna is composed of a parallelogram monopole, a ground plane with three symmetrical parasitic elements, and a 50‐Ω microstrip feedline. By using short‐circuited parasitic elements including a symmetrical parallelogram patch and a pairs of strip lines, the proposed antenna can excite extra resonate modes to achieve wideband operation. The measured results show that the proposed antenna offers a large impedance bandwidth for 10‐dB return loss is 4.74 GHz (1.82–6.56 GHz), corresponds to fractional bandwidth of 113% for central frequency at 4.19 GHz, and can cover the personal communication services, IMT‐2000, 2.4/5.2/5.8 GHz wireless local area network, and 2.5/3.5/5.5 GHz worldwide interoperability for microwave access standards. In addition, measured radiation patterns exhibit reasonable radiation characteristics. © 2012 Wiley Periodicals, Inc.
