Moreover, the single layer and thinness of this design are additional advantages over other broadband MM absorbers. Method Summary Simulations We used a finite-element-method-based ANSYS HFSS19 in our simulations. In Fig. 1b, the boundary is considered as the master/slave pair, and the ...
In this paper, a conical horn antenna has been designed for Ultra-Wideband applications by loading its section with a metamaterial. The work aims first to compare results obtained by the wavelet-moment method to a simulation performed using HFSS. Secondly the conical horn is loaded with a very...
The proposed miniaturized metamaterial multiband antenna depicted in Fig. 2, has been studied using HFSS v.13.0 software and is printed on FR4 substrate having dielectric constant, thickness and loss tangent of 4.4, 1.6 mm and 0.01 respectively, as illustrated in Fig. 8. The antenna has a ...
The proposed antenna is simulated using the HFSS simulator tool. Conclusion The presented research work provides the solution for simple, miniaturization, and broadband electrically small antenna design.

With software Ansoft HFSS, we simulated the properties of the proposed metamaterial and obtained the scattering parameters (S-parameters), which illustrates that the new metamaterial exhibits left-handed property within certain frequency ranges. Then we obtain the magnitude of S21 parameter from ...
