Abstract A novel, one‐piece, coupled‐fed, short‐circuited monopole antenna for wireless local area network applications in the 2.4‐GHz (2400–2484 MHz) band is proposed. The monopole is in the shape of an inverted hook, short circuited to a small antenna ground of size 10 × 15 mm 2 and capacitively excited by a driven coupling strip. The coupling strip is located in between the monopole and the ground by a tiny gap and grounded at one end. In this case, the antenna can be fabricated from a single metal plate at a low cost. The results showed that the antenna was very well matched with a return loss of 14 dB across the operating band and generated good dipole‐like, omnidirectional radiation patterns. Details of the design are discussed in this article. © 2012 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:936–940, 2012; View this article online at wileyonlinelibrary.com.
