This paper presents the design, optimization, and experimental validation of a triband star-shaped microstrip patch antenna for Ku-band applications. The design process begins with a single star-shaped patch antenna, which is progressively improved and extended to form a multiple-input multiple-output (MIMO) configuration. The final optimized MIMO antenna operates within 12–16 GHz, achieving resonances at 12.3 GHz, 14.2 GHz, and 15 GHz. The star-shaped geometry is employed to enhance the impedance bandwidth and improve gain performance. Simulated and measured results show good agreement in terms of return loss, impedance bandwidth, voltage standing wave ratio (VSWR), and radiation patterns. Moreover, diversity performance metrics, including the envelope correlation coefficient (ECC) and diversity gain (DG), confirm low correlation and near-ideal diversity across the three operating bands. The proposed triband MIMO antenna exhibits stable radiation performance and satisfactory gain, making it a strong candidate for 5G and satellite communication systems in the Ku-band.Refference:
