In this study, a rectangular quasi‐self‐complementary antenna for wireless local area network (WLAN) applications is presented. The antenna is composed of a rectangular radiating patch fed by a 50‐Ω microstrip line, its complementary structure, and a rectangular parasitic element. With appropriately modifying the dimensions of the antenna, a conventional wideband self‐complementary antenna can be redesigned into a novel dual‐band antenna. This feature makes the proposed antenna exhibit two impedance bandwidths of 100 MHz (about 4.1% at 2.45 GHz) and 2690 MHz (about 48.9% at 5.5 GHz), respectively. The measured results also indicate a good dipole‐like radiating performance and respectable peak gain values of the proposed antenna. Details of the antenna design process and the experimental results are discussed. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2179–2182, 2014
