Abstract:
The analysis and study of mutual coupling between two opposite microstrip antennas
help to investigate an efficient method for mine detection technique. The study involves
the effect of relative distance between two patches on the level of the mutual coupling
between them. Then the effect of placing a dielectric media above the antenna system
(to avoid the effective dielectric constant phenomenon), the system is then put over two
materials in order to judge (in an approximate manner), the effect of these materials on
the coupling level. Recording these responses, the effect of buried objects will clearly
appear as it will affect the previous coupling level received by the receiving antenna.
These results can be followed in steps to be applied as a mine detection technique. The
antenna system was fabricated, measured and the results were compared with the
simulations using both MoM, TLM numerical techniques.
