Microstrip Antenna For Detecting Buried Land Mines

Two patch array antennas have been proposed for detection of buried land mines using the mutual coupling effect. Mutual coupling among the edges of a patch or among the edges or nearby patches can influence the performance of microstrip antennas and arrays. The finite-difference time-domain method (FDTD) is used. The patch array antennas (sensor) have been simulated to detect various types of targets (nylon plate, stycast plate, and metal plate targets) in different types of soil properties
