11/3/2022 0 Comments Dragon curve ultra fractal![]() The simulation results of proposed antenna producing 7 frequency bands which serves Wi-Fi, WLAN, C-band, and X band wireless communications. The simulations have been carried out for both the antennas using ANSYS HFSS tool over the frequency sweep of (1-12GHz). To increase this antenna’s performance a meta material unit cell has been placed on the ground plane to serve multi band applications and is named as ANTENNA-2, which is the proposed antenna in this paper. ![]() In this paper a 2 nd order Koch fractal antenna of size 29.6 × 35.7mm ² designed on FR4-epoxy substrate material of dielectric constant (ɛ r ) 4.4 with a height of 1.6mm. Fractal antennas have been proved as a source for fulfilling these demands. The rapid advancements in wireless technology desires compact, miniaturized, multiband and ultra wideband antennas. DRAGON CURVE ULTRA FRACTAL FULL1.Here Antenna-1 is a 2 nd iteration Koch Fractal Antenna with Full Ground and Antenna-2 is the proposed antenna which is a modified version of Antenna-1 by changing its ground structure with a SRR Unit cell. DRAGON CURVE ULTRA FRACTAL PATCHHence their patch and ground Geometrical shapes are presented in the Fig. Geometries Of ANTENNA-1 and ANTENNA-2 In this work two antennas are being compared for their performance characteristics like Return loss, VSWR, Gain, %BW. A metamaterial triangular multiple SRRs positioned on the patch to make the antenna resonates for WLAN/WiMAX/ ITU band applications 2. An OSRR is placed on the defected ground which improves miniaturization and covers WLAN, WiMAX and X bands. ![]() The novel SPK gasket antennas were designed for L,S, C and X band communications with DGS,CSIR techniques. A hybrid antenna developed using Murkowski geometry and its results are compared for traditional SPK, Koch antennas. ![]() A circularly polarized Koch Fractal antenna developed for tri band applications covering WLAN and WiMAX. A wider bandwidth has obtained by maintaining the proper ratio of Koch fractal period and its radius A Koch snowflake generated on the patch and the tapering of dimensions allow the antenna to resonate at multiple bands within (0-8GHz) range. ![]()
