Abstract:
A printed slot antenna fed by a microstrip line with a diamond-shaped tuning stub for bandwidth enhancement is proposed and experimentally validated. The simulated results show that the impedance matching of the proposed rotated slot antenna is greatly affected by the dimension of the slot and by the size and the position of the diamond-shaped tuning stub. The experimental results demonstrate that the impedance bandwidth is over 123% for |S11|≤-10 dB ranging from 2.80 to 11.81 GHz. Moreover, the proposed antenna has a small size, and stable and omnidirectional radiation patterns are observed within the operating bandwidth.
