Design and Analysis of Log-Periodic Dipole Antenna as a Proximity Fuse Antenna

This paper deals with design and analysis of a proximity fuse antenna. The main requirement of a proximity fuse is that it should send a signal when the device is close to the target. A log-Periodic antenna is tested for various parameters like gain, directivity, VSWR and the radiation pattern is found which is most suitable for the operation. Simulation software CADFEKO is used to get the optimization design of LPDA.The software is used as it takes much less time and is cheaper compared to traditional antenna design methods.
