Design and Performance Evaluation of a High Gain Compact 10GHz Inset-Fed Rectangular Microstrip Patch Antenna for Advanced Wireless Communication Systems

This paper presents the design and performance evaluation of a high-gain compact 10GHz inset-fed microstrip patch antenna (MPA) for advanced wireless communication systems. The antenna is designed on Rogers RT5880 substrate with a size of 30.7 x 27.9 mm2, making it suitable for compact and portable wireless devices. The antenna's reflection coefficient is -33dB, and VSWR is 1.04, indicating excellent impedance matching. The antenna's gain is 7.98dBi, and its directivity is 8.71dBi, indicating high radiation efficiency and directionality. The antenna's efficiency is 84.5 percent, indicating low power losses due to absorption or other losses. The H-field side lobe is -15.3 dB, and the E-field side lobe is -15.2 dB, indicating low sidelobe levels. The proposed antenna can be used in a wide range of advanced wireless communication systems, such as point-to-point communication, wireless sensors, and satellite communication. The simulation results show that the proposed antenna performs well in terms of radiation characteristics and can be a good candidate for various wireless communication applications
