Abstract
This study has integrated PIN diode switching circuit with the smart antenna of 4×4 Butler Matrix and successfully designed a novel system. A 76 mm×130 mm×1.67 mm switching circuit is fabricated in this study. It is found that the switching circuit can perform better at Industrial, Scientific, and Medical (ISM) frequency of 2.45 GHz with the superior return loss of -33.98 dB. In order to test the switching circuit that operates properly with the Butler Matrix, the radiating pattern of each output of the integrated PIN diode switching circuit as well as Butler Matrix has been simulated. The obtained results show satisfactory performance and good agreement with the simulated results.
