Description

This study investigates the applications of electromagnetic wave theory in antenna design and radio frequency (RF) engineering for modern wireless communication systems. Electromagnetic waves play a vital role in wireless technologies including 5G/6G communication, satellite systems, radar, Internet of Things (IoT), and software-defined radio (SDR). The research analyzes how wave properties such as frequency, wavelength, polarization, and phase influence antenna performance and RF signal transmission. Numerical simulations were carried out using CST Microwave Studio and ANSYS HFSS to evaluate antenna gain, bandwidth, impedance matching, and radiation characteristics. The analysis showed that a 28 GHz phased-array antenna achieved a simulated gain of 21.6 dBi with beam steering capability up to ±45°. A massive MIMO configuration improved spectral efficiency by approximately 3.8 times compared to single-antenna systems. In addition, a microstrip patch antenna operating at 3.5 GHz produced a return loss of −28.4 dB and VSWR of 1.08, indicating excellent impedance matching. The findings demonstrate that proper electromagnetic wave engineering significantly enhances communication reliability, antenna efficiency, and RF system performance in advanced wireless networks.
