Abstract
This paper presents a wing-shaped ultra-wide band monopole antenna and its dual band-notch operations. Over a partial ground plane, the proposed antenna is designed with a wing-shaped radiating patch by connecting four circular conductors at both top-sides of the feedline. The antenna operates within 3.1∼15.36 GHz with a fractional bandwidth (-10 dB) of 132.83 by covering a small area of 25× 35 mm2 on a Rogers RT5880 substrate. Impedance matching of the antenna is stable due to its -17 dB bandwidth of 8.55 GHz and 58 dB minimum return loss. Peak gain of the antenna is 5.09 dBi while an average gain of 3.61 dBi is maintained over the entire -10 dB bandwidth of 12.26 GHz. Simulated average radiation efficiency is 99 and total efficiency is 94 in the proposed antenna. For band-notches, two slot-lines are applied on the upper part of the radiating patch where the first slot eliminates the 5G band at 3.5 GHz and the second slot eliminates the WLAN band at 5.8 GHz frequencies from the antenna bandwidth without hampering the overall performance. The proposed antenna is expected to be useful for ultra-wide band integrated communication systems. © 2021 IEEE.
