Antenna is an indispensable part of wireless communication. In particular, the microstrip patch antenna has gained significant popularity due to its distinctive advantages in terms of compactness, ease of manufacturing, and low energy requirements. On the other hand, microstrip patch antenna suffers from several practical limitations such as small bandwidth, low gain, and less efficiency with decreasing size, etc. With the advent of smartphones and smart IoT devices, the necessity of a compact and robust antenna has reached an unprecedented level. However, designing such an antenna is challenging due to various physical properties of antenna components, undesirable side-effects, and conflicting requirements. This report presents a compact and lightweight Rectangular Microstrip Patch Antenna (RMPA) design to address the aforementioned limitations. The proposed, designed antenna operates at a 2.45 GHz ISM band suitable for WLAN application. The design has been simulated in CST Studio Suite 2015 software. Critical analysis of simulation results reveals superior antenna performance compared to state-of-the-art designs available in the literature. The suggested single element compact designed RMPA antenna shows low return loss (–47.208 dB), VSWR (1.009) and gain (3.18 dB), high directivity (5.18 dBi), and efficiency (61.57%).
