A major concern for oil companies is the maintenance of oil pipelines. The contamination of
the soil is caused by oil leaks from underground pipelines. Using GPR, contaminated soil
sites can be located and characterized rapidly and relatively inexpensively without fracturing
or spreading contamination. The antenna system is one of the most critical hardware
components for GPR performance. To detect soil contamination, an L-band pyramidal horn
antenna is designed and simulated at frequencies between 1 and 2 GHz. Modelling the …

Maintenance of oil pipelines is an issue of great concern for oil companies. Soil
contamination is caused by oil leaks from underground pipelines. Ground penetrating radar
(GPR) is a rapid and relatively inexpensive technique used for locating and characterizing
soil contaminated sites without producing fractures and causing further migration of
contaminants. One of the most critical hardware components for the performance of GPR is
the antenna system. The present paper reports on the design and simulation of a pyramidal …
