Perancangan Butler Matrix 12x12 Untuk Platform Radar Antena Cerdas Pada 9,3 Ghz

---

ABSTRACT
This study discusses the design and performance evaluation of the Butler
Matrix in 2x2, 3x3, 4x4, and 12x12 configurations, integrated with MIMO
antennas for applications at a working frequency of 9.3 GHz in the X-Band
frequency band. This research is intended as part of the development of a smart
antenna-based radar platform that requires a power-sharing system with the
ability to control the direction of signal propagation. The results of the study
indicate that most of the hybrid coupler, crossover, phase shifter, and various
Butler matrix configurations (2x2, 3x3, 4x4, and 12x12) have good performance,
with return loss below –10 dB and phase deviation below 10°. The 2x2 and 4x4
configurations show the most optimal performance, with balanced power
distribution and beam direction as designed. However, in complex configurations
such as 12x12 and some phase shifters, significant performance degradation
occurs due to structural complexity, impedance imbalance, and cumulative losses.
Integration with MIMO antennas indicates that while some configurations meet
the expected radiation and port-to-port isolation characteristics, discrepancies
between simulation results and testing are still observed. Based on the research
findings, further optimization is required in controlling transmission losses and
phase matching, particularly in complex configurations.
Keywords: Butler Matrix, MIMO, smart antenna, X-Band, return loss, isolation,
radiation pattern, radar.
