Design and Optimization of C Structured Microstrip Multiband Antenna for Wireless Communication Using Fractal Geometry

Received Date:17 January 2023, Accepted Date:08 July 2023, Published Date:14 August 2023


Objectives: To develop a microstrip antenna with a C structure utilizing fractal geometry to minimize the antenna’s size and for more multiband frequency components which are useful in wireless applications. Method: This paper presents multiband C shaped microstrip multiband patch antenna. There are two iterations have been applied one by one on square patch which results in fractal patch antenna The IE3D software application has been used to simulate every designed microstrip antenna which resonates at 4.7 GHz, 6.5 GHz at corresponding frequencies.. With the use of this antenna design simulation tool, parametric analyses were done to establish the antenna’s geometries. A maximum of two iterations were made to the developed antenna in order to run it in multiband and make it appropriate for wireless applications including WIFI, ISM, and satellite C band. Proposed antenna is designed using IE3D and results are analyzed in terms of gain, return loss, directivity, bandwidth and VSWR. Findings: This design makes constructing a microstrip patch C-shaped fractal antenna for ISM and WIFI applications possible at a reasonable cost using a basic FR4 substrate which is cheaper as compared to RT Duroid and other substrates. It features a new shape for its patch and does not just cover a favorable bandwidth. Future assessments may find the antenna to be a good contender due to its compact size, needed bandwidth, more number of multiband and acceptable gain in contrast to antennas that have already been built or manufactured. Novelty and Applications: TheIE3D software has been used to run every simulation. The C-shaped antenna’s small size (28.83X37.26mm2), seven multiband and desired bandwidth with acceptable gain compared to design or fabricated antennas reported earlier. The comparison between the simulated and the measured results is incorporated in the manuscript. A comparison of the presented design with other articles is included to check the novelty of the design. The proposed method helps to target applications such as WiFi, Earth observation and microwave links.
