摘要

The objective of the Internet-based coaxial switching system for an amateur radio station with multiple antenna was to create a system that could choose the appropriate antenna for a radio station in order to reduce the mismatch problem. That is essential because each antenna has specific operating frequency and specific radiation pattern. To control the switching mechanism, the microcontroller was an essential part of this embedded system. The system was implemented with high quality relays having good response in the amateur radio frequency range. System control could be done through personal computer or Android mobile phone. In addition, this system was integrated with a software-defined receiver. The implemented system was capable of selecting appropriate antenna as designed. The attenuation loss and signal reflection were acceptable by conventional amateur radio standards. This system has a user-friendly interface via mobile phone and personal computer. In addition to regular amateur radio setup, this work was tested with a software-defined receiver and it could operate in the similar designed conditions.
