A novel printed monopole antenna for dual‐band operation is presented. The antenna comprises a radiator having a strip and two side‐loaded patches, and is fed by a microstrip feedline. By folding top one of the side‐loaded patches on the other side of the substrate as well as connecting the two patches by a short pin, good antenna performances including dual wide bandwidths of 590 MHz and 1.12 GHz, high antenna gains of ≥2.5 and 3.6 dBi, and monopole‐like radiation patterns over the two operating bands, respectively, are obtained. The measured results show good agreement with the simulated ones and sufficiently cover the operation requirements of the 2.4/5.2/5.8 GHz wireless local area network communication system. © 2011 Wiley Periodicals, Inc.
