摘要：A compact, fork-shaped patch antenna for tri-band applications with good bandwidth and isolation characteristics is presented in this paper. The proposed antenna resonates at the frequencies of 13.6 GHz, 15.5 GHz and 18.6 GHz respectively. A 2×2 MIMO (Multiple Input Multiple Output) system is developed using the proposed antenna giving an excellent isolation of more than 20 dB in the entire operating band. The S-Parameters, VSWR (Voltage Standing Wave Ratio), correlation coefficient and radiation pattern of the proposed antenna are presented. The proposed antenna covers most of the Ku-band (12 to 18 GHz) making it suitable for satellite applications.
