Abstract

This project was to design and development of antenna rotational table for small size antenna radiation pattern. Small size antenna is referred to as a microstrip antenna which has a low profile, low weight and small in size. The antenna rotational table design and development consists of hardware and programming implementation. In order to meet the project requirement, a necessary study had been conducted for types of motor available in market. The study is needed to find the most appropriate motor for the table rotation. For microstrip antenna radiation pattern test, the motor must be able to rotate until 180o but more is better. Antenna radiates in all direction with a different signal level at each point of angle. Thus, a step by step motor is required. The motor will need a controller to run in a desired movement. A PIC is needed for the control purpose. A details study had been done to ensure how the selected motor and an appropriate PIC should be used. In the meantime, the controller circuit is designed and implemented for a complete system.
