Abstract :
This paper presents a compact multiband planar monopole microstrip antenna for WLAN applications. The proposed antenna with microstrip-fed structure is compact with a total size of 50mm×19mm×1.5mm. A prototype is constructed and tested. The measured results show good dual band operations with -10 dB impedance bandwidth of 15.68% and 84.67% centered at 2.5 GHz and 5 GHz respectively, which cover the 2.4/5.2/5.8 GHz WLAN operating bands. A new technique of using a combination of a slot in the radiating patch and a slit in the ground plane has been employed to achieve the multiband performance of the antenna. The proposed antenna exhibits good radiation performance in terms of gain, return loss, and compactness. A good agreement between the simulated and the experimental results is achieved.
