patch antenna with a low weight and low-profile structure is introduced. The antenna incorporates a stacked-patch configuration, a coupled annular ring, and conductive vias to increase the impedance bandwidth. The circular stacked microstrip patch antenna is designed using HFSS Software. The measurement results demonstrate that the antenna achieves impressive impedance bandwidths of 2.35–2.43 GHz Moreover, the antenna boasts a compact structure with a height of only 0.24311024 inch (equivalent to a free-space wavelength). This design is particularly well-suited for applications such as wireless local area networks as the results indicated by HFSS Software. The antenna is perfect to improve the gain performance.
Wireless communication systems use various types of antennas, each designed for specific applications, frequency bands, and performance requirements. Common types include dipole antennas, Yagi-Uda antennas, patch antennas, parabolic reflector antennas, helical antennas, patch array antennas, log-periodic antennas, horn antennas, and omnidirectional antennas. Dipole antennas are used in Wi-Fi routers, RFID systems, and amateur radio. Yagi-Uda antennas provide high gain and directivity for longdistance communication. Patch antennas are compact and lightweight, ideal for limited space integration. Parabolic reflector antennas focus radio waves onto a smaller feed antenna, while helical antennas provide circular polarization. Patch array antennas offer high gain, beam steering capabilities, and polarization diversity. Antenna design plays a critical role in the performance and efficiency of wireless communication systems.

1. INTRODUCTION Wireless communication systems use electromagnetic waves to transmit and receive data, revolutionizing communication by enabling mobility, flexibility, and connectivity across various applications. Wireless communication systems involve a transmitter, receiver, channel, antennas, modulation, and multiplexing. The transmitter converts information into electromagnetic signals, modulates them, and amplifies them for transmission. The receiver captures and demodulates the transmitted signals, extracting the original information.
1.1 Objectives The objective behind developing a low-profile low weight microstrip patch antenna for WLAN (Wireless Local Area Network) communications stems from the increasing demand for efficient and reliable wireless communication systems in both indoor and outdoor environments. With the proliferation of wireless devices and the growing need for high-speed internet access, WLAN technologies such as Wi-Fi have become ubiquitous in various settings including homes, offices, and public spaces. A this antenna is desirable for WLAN applications as it can operate at 2.4 GHz frequency band, providing flexibility and better coverage for different types of devices and environments.
Channel characteristics, such as attenuation, noise, and interference, influence the system's performance. Antennas facilitate transmission and reception, and modulation techniques like AM, FM, and PM are employed. Multiplexing techniques enable efficient sharing of the same communication channel. Protocols and standards ensure interoperability, reliability, and security. Wireless communication systems are used in various fields, including mobile communication, IoT devices, wireless sensor networks, satellite communication, and wireless LANs.
