In this study, a compact dual‐band antenna for wireless universal serial bus dongle applications is proposed. The proposed structure consists of a conventional folded monopole antenna (driven element) and a strip pattern that extends from the ground (GND) plane (shorten parasitic element). The proposed antenna exhibits triple‐resonance (f 1 , f 2 , and f 3 ). The first two resonance frequencies (f 1 and f 2 ) are generated by adding the shorted parasitic element. The third resonance frequency (f 3 ) is generated by the folded monopole antenna. The first resonance frequency (f 1 ) covers 2.4‐GHz wireless local area network (WLAN) service, whereas the second and third resonance frequencies (f 2 and f 3 ) cover 5.2/5.8‐GHz WLAN service. Thus, dual‐band operation for 2.4/5.2/5.8‐GHz WLAN service can be easily performed. The antenna occupies a small area of 7 × 20 mm 2 . It can be easily connected to the edge of the system GND plane or the supporting metal frame of a laptop computer. Details of the proposed antenna are presented and studied. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:2207–2213, 2015
