Rancang Bangun Antena Mimo 12×12 Elemen Pada Frekuensi 9,3 Ghz Untuk Aplikasi Beam-Forming Smart Radar Antena

---

ABSTRACT
Radar is a vital technology in monitoring and security systems, especially in archipelagic countries like Indonesia. One of its key components is the antenna, which functions to receive and transmit electromagnetic signals. Microstrip antennas are selected for their compact size, efficiency, and ease of integration. This study designs microstrip MIMO array antennas with 2×2, 4×4, 8×8, and 12×12 configurations at 9.3 GHz using Rogers RO3010 substrate and a series-fed array approach, integrated with a Butler matrix for beamforming. Simulation results show that the 12×12 array achieves a return loss of less than –10 dB, bandwidth of 51–55 MHz, beamwidth of 9.5°, directional radiation patterns, and gain up to 116 dBi. Measurement results indicate a frequency shift due to fabrication tolerances and impedance mismatch, which negatively affect return loss and mutual coupling. Furthermore, integration with the Butler matrix successfully produces simultaneous multiple beams. Experimental results on the 2×2 configuration confirm phase shifting, as evidenced by different main lobe directions for each port. Overall, the designed antenna demonstrates good performance for modern radar applications, despite deviations between simulation and measurement results.
