Abstract
Wireless technologies play a major role in remote communication systems and various wireless technologies are used to communicate at these remote locations. Technology is now all at hand. In this paper, a microstrip patch antenna in the 2.45 GHz S-band is designed and studied, which can be used in future wireless applications. The main goal of this antenna is low return loss, bringing the VSWR close to 1, to improve the gain, directivity, and efficiency of this antenna compared to other antennas. The said antenna has been designed and simulated using computer simulation technology software, where Roger RT duroid 5880 is used as substrate material. On the Roger RT-5880, the recommended antenna dimension has a height of 1.5 mm. This material has a relative permittivity that is equivalent to 2.2. Both the patch and the ground are made of copper, and the thickness is 0.035mm. The following findings emerged from running these simulations: resonance frequency of 2.45 GHz, return loss (S <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">11</inf> ) of-12.542 dB, bandwidth of 0.0349 GHz, gain of 8.092 dB, directivity of 8.587 dBi, and an efficiency of 94.24%. The findings that were acquired using this proposed antenna were superior to those that were obtained using existing antennas and reported in contemporary scientific journals and conferences. As a consequence of this, the requirements of many wireless communication applications are likely to be met by this antenna.
