A microstrip‐fed slot antenna design for wireless local area network 2.4/5 GHz applications is proposed. To achieve dual‐band operation that composed of four resonant modes located at approximately 2.28, 2.69, 5.36, and 5.94 GHz band, three separate slots are embedded into the ground plane, in which two of the slots are devised as step‐impedance types, and one of the slots is an L‐shaped slot type. By meticulously arranging the positions of these three slots located above the microstrip‐fed line, two broad operating bands that operate between 2140–2750 MHz (∼25%) and 5050–6160 MHz (∼20%) are achieved. Detail process of designing the proposed antenna is explicitly shown, and vital parametric studies were also conducted by simulation. © 2014 Wiley Periodicals, Inc.
