In this article, a new design of a compact printed rectangular antenna for wireless local area network (WLAN) applications in 802.11a is investigated. The defected ground structure (DGS) technique is successfully used to reduce the ground plane by cutting a large slot to achieve significant miniaturization. The ground plane structure consists of inverted ‘L’ shape. The rectangular radiating element has a size of 6 × 5 mm 2 and is connected to a microstrip transmission feed line. The simulated and measured resonance frequency of the single‐band antenna is approximately 5.8 GHz and may cover an impedance bandwidth of 1 GHz for the measurement and 1.65 GHz for the simulation. The simulated and the measured data are in good agreement. The proposed antenna is very compact (10 × 6 mm 2 ) and its impedance bandwidth is suitable for the 5.2‐5.8 GHz WLAN communication systems.
