Antenna is one of the backbone and frontend device to any communication systems used for wide variety of applications including traffic management and cellular mobile phones etc. The compact size and low profile of the optimal antenna is a notable feature, enhancing its suitability for integration into small devices. Its multi-band frequency response is obtained by inserting a rectangular slot on a radiating patch of antenna, allowing for precise tuning of operation frequencies. In this research paper, we proposed a rectangular patch antenna with shorting pins that leads to optimal antenna design methodology, for this design we have considered various dimensional calculations. With the help of these parameters, we have designed and simulated the antenna using Computer Simulation Technology (CST) Microwave Studio. We then analyzed the simulation results to ensure accuracy in predicting the antenna's performance parameters. The result produces an average gain of 3 dBi with a return loss of – 15 dBi. It has operating frequency range between 2 to 6 GHz. In addition to the desired frequency and gain, it also evaluates the key parameters including bandwidth, directivity, and radiation patterns. The proposed system improves connectivity and road safety through efficient, good, and dependable communication. Finally, it may lead to a better network connectivity with improved overall functionality as well as Quality of Service (QoS) of the communication devices. |
