Abstract

Antenna pattern measurement is a requirement for antenna characteristics determination. However, such sophisticated set-up measurement demands skilled authority. This project employed a low-cost RF detector (MAX4003) to capture the E-field and consequently assist in acquiring data for antenna radiation pattern. By fabricating a 3.0V circuit with MAX4003 and connecting to an Arduino, this compact module creates a basic interface between the antenna under test and user’s measurement PC. The results show the measured voltage from the RF detector is in good agreement with the manufacturer’s datasheet for 1.8GHz and 2.1GHz operating frequencies. The input power is also directly proportional to the output power. The project was further tested by conducting a full 360° antenna radiation pattern measurement. The results established a satisfying comparison to theoretical radiation pattern. Overall, the system benefits to individual such as students and researchers to replicate the same method in order to have a compact and attainable antenna measurement system.
