WebAug 20, 2024 · A compact asymmetric coplanar strip (ACS)-fed with Hilbert Curve Fractal Antenna (HCFA) is proposed for GSM (1.8 GHz), WiMAX (3.3 GHz) and WLAN (5.5 GHz) applications. The proposed antenna occupies a compact size of 18 × 16.5 × 1.6 mm 3 involving ACS feed line with HCFA and ground plane. Webtated and/or reflected. Figure 1 also shows the Hilbert curvea of order 2 and 3. When the order of the curve tends to infinity, the resulting curve is a fractal, with a fractal dimension of 2 [Man77]. The Hilbert curve can be generalized for higher dimensionalitiea. Algorithms

WebApr 5, 2024 · To increase the space utilization, each unit cell is arranged in space according to the Hilbert fractal curve. Consequently, a metasurface absorber with 6 detuned unit cells is constructed. The multiple resonant cavities with dissimilar lengths can provide peak absorptions at multiple frequencies, thereby broadening the attenuation frequency range.
