Abstract
This paper uses coaxial probe feed method to present, design, and simulate elliptical microstrip patch antenna at ISM band. This paper processes an innovative elliptical microstrip patch (MSPA) antenna at standard ISM frequency band ranges from 2.4 GHz to 2.5 GHz. The planned and simulated EMSPA operating frequency is 2.4 GHz to 2.5 GHz and 4.2, 4.4, 4.6 & 4.8 FR4 substrate, this selected frequency increases efficiency in terms of S <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</sub> and reasonable gain value. In this study, coaxial probes feed the proposed antenna fixed on an FR-4 substrate material which has 4.2, 4.4, 4.6 & 4.8 dielectric constant, substratum thickness is 6.6 mm. The intension of the proposed antenna is that to determine the higher gain, less S11 at different operating frequencies that are 2.35 GHz, 2.4 GHz, 2.45GHz and 2.5 GHz, which is the ISM band range. The high-performance systems such as rockets, ships, missiles and satellites use elliptical microstrip patch antennas. Antennas with optimal measurements of elliptical microstrip patches act as circularly polarized wave radiators. Various simulation antenna design software is available, such as FEKO, IE3D, CST, HFSS, Antenna Magus and MATLAB. Here, using MATLAB simulation software tool, the EMSPA is designed and simulated and also estimate the performance characteristics, such as s-parameter, vswr, EH fields, radiation pattern, current distribution, gain, elevation and azimuthal radiation pattern.
