Abstract :
A miniature printed H-shaped narrow slot antenna fed by a coplanar waveguide (CPW) is proposed for WLAN applications in the 2.4 GHz band. The antenna with a simplified open-end tuning stub is also proposed. The prototype has been designed and fabricated and found to have a bandwidth of 13.5%, and the radiation pattern measured at resonance is very close to omnidirectional in the H-plane. The characteristics of the proposed antenna has been investigated using simulation software HFSS and experimental results. The measured and simulated results show excellent agreement.
