Abstract

In current times, there is a growing need for compact antennas that can function in multiple bands, specifically for wireless communication systems such as GSM, UMTS, and WIFI. Researchers are exploring the use of fractal geometry antennas to address this requirement. Several recent investigations have revealed that these structures possess distinct features that enhance certain properties of low-profile antennas. To attain the desired performance characteristics, a thorough examination, analysis, design, and description of the Meander-like fractal structure is conducted. The proposed antenna was created through a series of iterations ranging from the first to fourth. The imperfect ground plane was introduced in the last iteration to achieve wideband characteristics. In order to optimize performance, various aspects of the antenna including its properties, input impedance, VSWR, reflection coefficient, and radiation patterns are analyzed. The CST Design Environment was utilized for both simulation and implementation purposes. After designing the antenna, the Proposed antenna final iteration has a lower control band of (2–4.63) GHz and the bandwidth is 2.63GHz this can be considered as wideband, mid control band of proposed fractal antenna is (5.15–6.05) GHz close to the resonant frequency 5.82 GHz and upper control band of (8.15–8.66) GHz around close to the resonant frequency of 8.45 GHz [1]. There is a variety of applications in which these bands can be utilized wirelessly, including IEEE 802.11a, Wi-MAX, WI-FI, HiperLAN/2, Digital Cellular System, Personal Communications Services, UMTS, Bluetooth, IEEE 802.11 b/g/n WLAN, GSM, and GPS.
