Abstract
A hybrid ground penetrating radar (GPR)/metal detector (MD) head includes a V-dipole GPR antenna and transmit and receive MD coils. One of the MD coils is arranged in a quadrupole configuration with a crossbar, and the V-dipole antenna is perpendicular to the crossbar. The legs of the V-dipole antenna may straddle the crossbar or may be on one side of the crossbar. The MD coils may be fabricated on a printed circuit board, which may be at a non-normal angle with respect to a central axis of the V-dipole antenna.
