Abstract

Antennae are the prior components in the lightning detection system. It is important to have effective and efficient antennae in order to detect the sensitive lightning event. Therefore, it is necessary to improve and evaluate the performance of the new antennae to make the lightning detection system more efficient. Capacitive antennae are the main part in this research in order to detect and evaluate the signal waveform whether it is which type of lightning occurring at that particular time. There are two types of antennae used in the lightning detection system which are capacitive antennae to detect electric field and loop antennae to detect magnetic field. Both antennae are in big size and not portable cause inconvenience. Thus, portable capacitive antennae with high sensitivity are designed. Compact stacked method is used in capacitive antennae by increasing the copper plate layer in between the parallel plate antennae. Performance analysis had been done by using CST software. The hardware is built and test in real-time raining event. The results are compared and shown that the parallel plate capacitive antennae (two FR4 board in square size) perform better than compact stacked capacitive antennae.
