Hussain Niamat,Syed Naheel Raza Rizv,Awan Wahaj Abbas 대한전기학회 2021 Journal of Electrical Engineering & Technology Vol.16 No.2
An electrically small ultra-wideband antenna for modern compact devices is presented in this paper. The antenna is constructed using a low-cost FR4 substrate, where etching slot and stub loading techniques are utilized to achieve miniaturization. The antenna comprises of simple geometrical structure with an overall size of 0.13 λ o × 0.19 λ o × 0.02 λ o ( λ o is the free-space wavelength at 3.5 GHz). A sample prototype was fabricated and tested to validate various performance parameters of the antenna. The antenna has measured 10 dB impedance bandwidth ranging from 3.55–12.16 GHz with a stable gain having a maximum value of 4.52 dBi. The performance comparison with state-of-the-art works shows that the proposed antenna off ers the advantages of miniaturized size, simple geometry along with competitive bandwidth and stable radiation characteristics.
