The Design, Simulation, and Measurement of a 30 GHz Microstrip Patch Antenna for Millimeter-Wave Applications

This study addresses the challenges of miniaturization and impedance matching for mmWave antennas to achieve efficient radiation in the desired frequency range. The problem statement focuses on the limitations of traditional antenna designs at mm Wave frequencies, which often result in bulky structures and poor impedance matching, leading to suboptimal radiation characteristics. To address these challenges, this study describes the design, simulation, and measurement of a 30 GHz microstrip patch antenna. With a measured reflection coefficient of −19.25 dB and a gain of 7.65 dB, the aerial structure strikes a chord at 30 GHz. It measures 14 × 18 × 0.586 mm3. The results of the measurements show that the proposed design is appropriate for millimeter wave band 5G wireless applications. The key innovation lies in enabling the antenna to be significantly smaller compared to conventional designs. The proposed impedance matching techniques further enhance the antenna's efficiency and radiation characteristics. The results demonstrate a significant improvement in the antenna's miniaturization, gain, and directivity when compared to traditional mmWave antenna designs. Extensive simulations and measurements validate the proposed design's performance in controlled environments.
